The undecorated child migration creates a synthetic decorator, which
contained `"exportAs": ["exportName"]` as obtained from the metadata of
the parent class. This is a problem, as `exportAs` needs to specified
as a comma-separated string instead of an array. This commit fixes the
bug by transforming the array of export names back to a comma-separated
string.

When ngcc is analyzing synthetically inserted decorators from a
migration, it is typically not expected that any diagnostics are
produced. In the situation where a diagnostic is produced, however, the
diagnostic would not be reported at all. This commit ensures that
diagnostics in migrations are reported.

The compiler exports a `formatDiagnostics` function which consumers can use
to print both ts and ng diagnostics. However, this function was previously
using the "old" style TypeScript diagnostics, as opposed to the modern
diagnostic printer which uses terminal colors and prints additional context
information.
This commit updates `formatDiagnostics` to use the modern formatter, plus to
update Ivy's negative error codes to Angular 'NG' errors.
The Angular CLI needs a little more work to use this function for printing
TS diagnostics, but this commit alone should fix Bazel builds as ngc-wrapped
goes through `formatDiagnostics`.

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.

In Ivy, if you do:
`TestBed.configureTestingModule({providers: [{provide: Service}]});`
the injector will attempt to inject Service as if it was simply listed
in the providers array like `{providers: [Service]}`
This fixes an inconsistency when similarly providing an override with no
`useValue` or `useFactory`.

Previously the JIT evaluated code for ivy localized strings included
backtick tagged template strings, which are not compatible with ES5
in legacy browsers such as IE 11.
Now the generated code is ES5 compatible.

Prior to this commit, calling change detection for destroyed views resulted in errors being thrown in some cases. This commit adds a check to make sure change detection is invoked for non-destroyed views only.

Previously, ternary expressions were emitted as:
condExpr ? trueCase : falseCase
However, this causes problems when ternary operations are nested. In
particular, a template expression of the form:
a?.b ? c : d
would have compiled to:
a == null ? null : a.b ? c : d
The ternary operator is right-associative, so that expression is interpreted
as:
a == null ? null : (a.b ? c : d)
when in reality left-associativity is desired in this particular instance:
(a == null ? null : a.b) ? c : d
This commit adds a check in the expression translator to detect such
left-associative usages of ternaries and to enforce such associativity with
parentheses when necessary.
A test is also added for the template type-checking expression translator,
to ensure it correctly produces right-associative expressions for ternaries
in the user's template.

Remove the remaining check for compile build variable in the ng_module
rule. Now that components is no longer relying on this build variable
we can safely remove it from our repository.
We will leave the remaining check for if the compile build variable is
used within our own repo, with plans to remove it in a couple months.
It is being kept in place to ensure that uncommitted local scripts for
our own development that we have locally, kill error as expected if
they still reference the compile build variable.

Before updating to remove the compile build variable, we must update
the components unit test integrations to a sha in the components
repo which no longer relies on the compile build variable.

Adds the ability to expose global symbols in the API docs via the `@globalApi` tag. Also supports optionally setting a namespace which will be added to the name automatically (e.g. `foo` will be renamed to `ng.foo`). Relevant APIs should also be exported through the `global.ts` file which will show up under `core/global`.

Due to a bug in the existing banner, `typescript` module was require-d
instead of reusing the module passed in from tsserver.
This bug is caused by some source files in language-service that imports
`typescript` instead of `typescript/lib/tsserverlibrary`.
This is not an unsupported use case, it's just that when typescript is
resolved in the banner we have to be very careful about which modules to
"require".
The convoluted logic in the banner makes it very hard to detect
anomalies. This commit cleans it up and removes a lot of unneeded code.
This commit also removes `ts` import in typescript_host.ts and use `tss`
instead to make it less confusing.
