The problem was caused by missing `allocateBindingSlots` that led to incorrect # of vars defined for components and as a result, causing errors at runtime. Now all `bind` operation are accounted for and the number of `vars` is correct.

The problem was caused by the self-closing i18n instruction that was generated in case we have styling instructions defined for a component. As a result, that caused problems at runtime. This update adds extra check to avoid creating self-closing i18n instructions (create i18nStart and i18nEnd instructions instead) when styling instructions are present.

Ngcc will now render additional exports for classes that are referenced in
`NgModule` decorated classes, but which were not publicly exported
from an entry-point of the package.
This is important because when ngtsc compiles libraries processed by ngcc
it needs to be able to publcly access decorated classes that are referenced
by `NgModule` decorated classes in order to build templates that use these
classes.
Doing this re-exporting is not without its risks. There are chances that
the class is not exported correctly: there may already be similarly named
exports from the entry-point or the class may be being aliased. But there
is not much more we can do from the point of view of ngcc to workaround
such scenarios. Generally, packages should have been built so that this
approach works.

There are a number of variables that need to be passed around
the program, in particular to the renderers, which benefit from being
stored in well defined objects.
The new `EntryPointBundle` structure is a specific format of an entry-point
and contains the compiled `BundleProgram` objects for the source and typings,
if appropriate.
This change helps with future refactoring, where we may need to add new
properties to this object. It allows us to maintain more stable APIs between
the constituent parts of ngcc, rather than passing lots of primitive values
around throughout the program.

The `NgModuleDecoratorHandler` can now register all the references that
it finds in the `NgModule` metadata, such as `declarations`, `imports`,
`exports` etc.
This information can then be used by ngcc to work out if any of these
references are internal only and need to be manually exported from a
library's entry-point.

By inverting the relationship between `EntryPointPaths` and
`EntryPointFormat` we can have interfaces rather than types.
Thanks to @gkalpak for this idea.

If a decorated class is not publicly exported via an entry-point then the
previous approach to finding the associated typings file failed.
Now we ensure that we extract all the class declarations from the
dtsTypings program, even if they are not exported from the entry-point.
This is achieved by also parsing statements of each source file, rather
than just parsing classes that are exported from the entry-point.
Because we now look at all the files, it is possible for there to be multiple
class declarations with the same local name. In this case, only the first
declaration with a given name is added to the map; subsequent classes are
ignored.
We are most interested in classes that are publicly exported from the
entry-point, so these are added to the map first, to ensure that they are
not ignored.

Previously the concept of multiple directives with the same selector was
not supported by ngtsc. This is due to the treatment of directives for a
component as a Map from selector to the directive, which is an erroneous
representation.
Now the directives for a component are stored as an array which supports
multiple directives with the same selector.
Testing strategy: a new ngtsc_spec test asserts that multiple directives
with the same selector are matched on an element.

These tests are not relevant to Ivy:
//packages/compiler-cli/test/diagnostics:check_types
//packages/compiler-cli/test/diagnostics:expression_diagnostics
//packages/compiler-cli/test/transformers:test
//packages/compiler-cli/test:extract_i18n
The //packages/compiler-cli/test:ngtools_api test has 2 specs, one of
which passes and the other of which depends on ngtsc supporting lazy
routes. It's now disabled with fixmeIvy().

These paths are no longer needed / used.
I had to disable one jit mode spec because it fails now that we actually run it.
I root caused the jit test failure as missing forwardRef support. See FW-645.

When ngtsc compiles @angular/core, it rewrites core imports to the
r3_symbols.ts file that exposes all internal symbols under their
external name. When creating the FESM bundle, the r3_symbols.ts file
causes the external symbol names to be rewritten to their internal name.
Under ngcc compilations of FESM bundles, the indirection of
r3_symbols.ts is no longer in place such that the external names are
retained in the bundle. Previously, the external name `ɵdefineNgModule`
was explicitly declared internally to resolve this issue, but the
recently added `setClassMetadata` was not declared as such, causing
runtime errors.
Instead of relying on the r3_symbols.ts file to perform the rewrite of
the external modules to their internal variants, the translation is
moved into the `ImportManager` during the compilation itself. This
avoids the need for providing the external name manually.

Now that the Ivy switch transform uses ts.getMutableClone() to copy
statements, there's no need to set .parent pointers on the resulting
updated nodes. Doing this was causing assertion failures deep in
TypeScript in some cases.
