Currently if an Angular library has multiple unnamed module re-exports, NGC will
generate incorrect metdata if the project is using the flat-module bundle option.
e.g.
_public-api.ts_
```ts
export * from '@mypkg/secondary1';
export * from '@mypkg/secondary2';
```
There are clearly two unnamed re-exports in the `public-api.ts` file. NGC right now
accidentally overwrites all previous re-exports with the last one. Resulting in the
generated metadata only containing a reference to `@mypkg/secondary2`.
This is problematic as it is common for primary library entry-points to have
multiple re-exports (e.g. Material re-exporting all public symbols; or flex-layout
exporting all public symbols from their secondary entry-points).
Currently Angular Material works around this issue by manually creating
a metadata file that declares the re-exports from all unnamed re-exports.
(see: https://github.com/angular/material2/blob/master/tools/package-tools/build-release.ts#L78-L85)
This workaround works fine currently, but is no longer easily integrated when
building the package output with Bazel. In order to be able to build such
libraries with Bazel (Material/flex-layout), we need to make sure that NGC
generates the proper flat-module metadata bundle.

Currently if developers use call expressions in their static
class members ([like we do in Angular](https://github.com/angular/angular/blob/master/packages/core/src/change_detection/differs/keyvalue_differs.ts#L121)),
the metadata that is generated for flat modules is invalid. This
is because the metadata bundler logic currently does not handle
call expressions in static class members and the symbol references
are not rewritten to avoid relative paths in the bundle.
Static class members using a call expression are not relevant for
the ViewEngine AOT compilation, but it is problematic that the
bundled metadata references modules using their original relative
path. This means that the bundled metadata is no longer encapsulated
and depends on other emitted files to be emitted in the proper place.
These incorrect relative paths can now cause issues where NGC
looks for the referenced symbols in the incorrect path. e.g.
```
src/
| lib/
| index.ts -> References the call expression using `../../di`
```
Now the metadata looks like that:
```
node_modules/
| @angular/
-- | core/
-- -- | core.metadata.json -> Says that the call expr. is in `../../di`.
| di/
```
Now if NGC tries to use the metadata files and create the summary files,
NGC resolves the call expression to the `node_modules/di` module. Since
the "unexpected" module does not contain the desired symbol, NGC will
error out.
We should fix this by ensuring that we don't ship corrupted metadata
to NPM which contains relative references that can cause such
failures (other imports can be affected as well; it depends on what
modules the developer has installed and how we import our call
expressions).
Fixes#28741.

* Currently when building a `ng_module` with Bazel and having the flat module id option set, the flat module files are not being generated because `@angular/compiler-cli` does not properly determine the entry-point file.
Note that this logic is not necessarily specific to Bazel and the same problem can happen without Bazel if multiple TypeScript input files are specified while the `flatModuleIndex` option has been enabled.

The current module resolution simply attaches .ts to the import/export path, which does
not work if the path is using Node / CommonJS behavior to resolve to an index.ts file.
This patch uses typescript's module resolution logic, and will attempt to load the original
typescript file if this resolution returns a .js or .d.ts file

All errors for existing fields have been detected and suppressed with a
`!` assertion.
Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that
the new syntax causes tsickle emitted node to no longer track their
original sourceFiles.

Currently, the flat module index metadata is produced directly from
the source metadata. The compiler, however, applies transformations
on the Typescript sources during transpilation, and also equivalent
transformations on the metadata itself. This transformed metadata
doesn't end up in the flat module index.
This changes the compiler to generate the flat module index metadata
from its transformed version instead of directly from source.

This allows a bundle index to be re-exported by a higher-level module without fear of collisions.

InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this
requires a runtime reflection system in order to generate factories
from expressed provider declarations.
Instead, this change requires scoped InjectionTokens to provide the
factory directly (likely using inject() for the arguments), bypassing
the need for a reflection system.

Folding errors passed calls prevented the static reflector from

- temporarily keeps the old sources under packages/tsc-wrapped

- removes the compiler options `disableTransformerPipeline` that was introduced
in a previous beta of Angular 5, i.e. the transformer based compiler
is now always enabled.
