This patch removes the need for the styleSanitizer() instruction in
favor of passing the sanitizer into directly into the styleProp
instruction.
This patch also increases the binding index size for all style/class bindings in preparation for #34418

Pipes in host binding expressions are not supported in View Engine and Ivy, but in some more complex cases (like `(value | pipe) === true`) compiler was not reporting errors. This commit extends Ivy logic to detect pipes in host binding expressions and throw in cases bindings are present. View Engine behavior remains the same.

Typescript 3.7 now emits d.ts files for getters differently than prior versions,
and there seems to be a bug in how it strips private types without replacing them
with explicit 'any' type. This then leads to compilation failures in projects compiled
against our packages that don't have skipLibCheck turned on but do have strict or
noImplicitAny check on.
I'm working around this by marking the affected getters as @internal and
adding a test to prevent future regressions.
I believe this is a TypeScript bug, and I filed a bug report:

The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.

The `getProjectAsAttrValue` in `node_selector_matcher` finds the
ProjectAs marker and then additionally checks that the marker appears in
an even index of the node attributes because "attribute names are stored
at even indexes". This is true for "regular" attribute bindings but
classes, styles, bindings, templates, and i18n do not necessarily follow
this rule because there can be an uneven number of them, causing the
next "special" attribute "name" to appear at an odd index. To address
this issue, ensure ngProjectAs is placed right after "regular"
attributes.

Prior to this commit, there were no `advance` instructions generated before `i18nExp` instructions and as a result, lifecycle hooks for components used inside i18n blocks were flushed too late. This commit adds the logic to generate `advance` instructions in front of `i18nExp` ones (similar to what we have in other places like interpolations, property bindings, etc), so that the necessary lifecycle hooks are flushed before expression value is captured.

In the past, only the starting index of an expression Token has been
recorded, so a parser could demarkate the span of a token only by the
start locations of two tokens. This may lead to trailing whitespace
being included in the token span:
```html
{{ token1 + token2 }}
^^^^^^^^^ recorded span of `token1`
```
It's also not enough for a parser to determine the end of a token by
adding the length of the token value to the token's start location,
because lexed expression values may not exactly reflect the source code.
For example, `"d\\"e"` is lexed as a string token whose value is `d"e`.
Instead, this commit adds a `end` field to expression tokens. `end`
is one past the last index of the token source code. This will enable a
parser to determine the span of a token just by looking at that token.
This is a breaking change because the contructor interface of `Token`
has changed.

Previously, the type checker would compute an absolute source span by
combining an expression AST node's `ParseSpan` (relative to the start of
the expression) together with the absolute offset of the expression as
represented in a `ParseSourceSpan`, to arrive at a span relative to the
start of the file. This information is now directly available on an
expression AST node in the `AST.sourceSpan` property, which can be used
instead.

Previously the identifiers used in the typings files were the same as
those used in the source files.
When the typings files and the source files do not match exactly, e.g.
when one of them is flattened, while the other is a deep tree, it is
possible for identifiers to be renamed.
This commit ensures that the correct identifier is used in typings files
when the typings file does not export the same name as the source file.

Previously, bound events were incorrectly bound to directives with
inputs matching the bound event attribute. This fixes that so bound
events can only be bound to directives with matching outputs.
Adds tests for all kinds of directive matching on bound attributes.

Expressions in an inline template binding are improperly recorded as
spaning an offset calculated from the start of the template binding
attribute key, whereas they should be calculated from the start of the
attribute value, which contains the actual binding AST.

Avoids the usage of array destructuring, as it introduces calls to
a `__values` helper function in ES5 that has a relatively high
performance impact. This shaves off roughly 130ms of CPU time for a
large compilation with big templates that uses i18n.

The template parser has a certain interpolation config associated with
it and builds a regular expression each time it needs to extract the
interpolations from an input string. Since the interpolation config is
typically the default of `{{` and `}}`, the regular expression doesn't
have to be recreated each time. Therefore, this commit creates only a
single regular expression instance that is used for the default
configuration.
In a large compilation unit with big templates, computing the regular
expression took circa 275ms. This change reduces this to effectively
zero.

On a large compilation unit with big templates, the total time spent in
the `PlainCharacterCursor` constructor was 470ms. This commit applies
two optimizations to reduce this time:
1. Avoid the object spread operator within the constructor, as the
generated `__assign` helper in the emitted UMD bundle (ES5) does not
optimize well compared to a hardcoded object literal. This results in a
significant performance improvement. Because of the straight-forward
object literal, the VM is now much better able to optimize the memory
allocations which makes a significant difference as the
`PlainCharacterCursor` constructor is called in tight loops.
2. Reduce the number of `CharacterCursor` clones. Although cloning
itself is now much faster because of the optimization above, several
clone operations were not necessary.
Combined, these changes reduce the total time spent in the
`PlainCharacterCursor` constructor to just 10ms.

To create a binding parser, an instance of `ElementSchemaRegistry` is
required. Prior to this change, each time a new binding parser was
created a new instance of `DomElementSchemaRegistry` would be
instantiated. This is an expensive operation that takes roughly 1ms per
instantiation, so it is key that multiple allocations are avoided.
By sharing a single `DomElementSchemaRegistry`, we avoid two such
allocations, i.e. save ~2ms, per component template.

The `ModuleWithProviders` type has an optional type parameter that
should be specified to indicate what NgModule class will be provided.
This enables the Ivy compiler to statically determine the NgModule type
from the declaration files. This type parameter will become required in
the future, however to aid in the migration the compiler will detect
code patterns where using `ModuleWithProviders` as return type is
appropriate, in which case it transforms the emitted .d.ts files to
include the generic type argument.
This should reduce the number of occurrences where `ModuleWithProviders`
is referenced without its generic type argument.

Occasionally a factory function needs to be generated for an "invalid"
constructor (one with parameters types which aren't injectable). Typically
this happens in JIT mode where understanding of parameters cannot be done in
the same "up-front" way that the AOT compiler can.
This commit changes the JIT compiler to generate a new `invalidFactoryDep`
call for each invalid parameter. This instruction will error at runtime if
called, indicating both the index of the invalid parameter as well as (via
the stack trace) the factory function which was generated for the type being
constructed.

If the `ngI18nClosureMode` global check actually makes it
through to the runtime, then checks for its existence should
be guarded to prevent `Reference undefined` errors in strict
mode.
(Normally, it is stripped out by dead code elimination during
build optimization.)
This comment ensures that generated template code guards
this global check.

Prior to this commit, if a template (for example, generated using structural directive such as *ngIf) contains `ngProjectAs` attribute, it was not included into attributes array in generated code and as a result, these templates were not matched at runtime during content projection. This commit adds the logic to append `ngProjectAs` values into corresponding element's attribute arrays, so content projection works as expected.
