Alex Rickabaugh f99cb5c995 fix(compiler-cli): flat module index metadata should be transformed (#23129)
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.

Alex Rickabaugh 550433a128 feat(compiler-cli): lower loadChildren fields to allow dynamic module paths (#23088)
Computing the value of loadChildren does not work externally, as the CLI
needs to be able to detect the paths referenced to properly set up
codesplitting. However, internally, different approaches to codesplitting
require hashed module IDs, and the computation of those hashes involves
something like:

{path: '...', loadChildren: hashFn('module')}

ngc should lower loadChildren into an exported constant in that case.

This will never break externally, because loadChildren is always a
string externally, and a string won't get lowered.

This adds compilation of @NgModule providers and imports into

Alex Rickabaugh 6e00410e1c fix(compiler-cli): annotate Ivy fields as @nocollapse in closure mode (#22691)
Closure has a transformation which turns:

Service.ngInjectableDef = ...;

into:

Service$ngInjectableDef = ...;

This transformation obviously breaks Ivy in a major way. The solution is
to annotate the fields as @nocollapse. However, Typescript appears to ignore
synthetic comments added to a node during a transformation, so the "right"
way to add these comments doesn't work.

As an interim measure, a post-processing step just before the compiled JS is
written to disk appends the correct comments with a regular expression.

Alex Rickabaugh 0d8deb0795 fix(compiler-cli): generate proper exports.* identifiers in cjs output (#22564)
When the compiler generates a reference to an exported variable in the
same file, it inserts a synthetic ts.Identifier node. In CommonJS
output, this synthetic node would not be properly rewritten with an
`exports.` prefix.

This change sets the TS original node property on the synthetic node
we generate, which ensures TS knows to rewrite it in CommonJS output.

Alex Rickabaugh f755db78dc fix(core): require factory to be provided for shakeable InjectionToken (#22207)
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.

Alex Rickabaugh 235a235fab feat: change @Injectable() to support tree-shakeable tokens (#22005)
This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.

Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".

Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.

Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.

Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

Martin Probst 8c52088346 fix(compiler-cli): merge @fileoverview comments. (#20870)
Previously, this code would unconditionally add a @fileoverview

However often existing fileoverview comments should be copied from the
file the generated file was originally based off of. This allows users
to e.g. include Closure Compiler directives in their original
`component.ts` file, which will then automaticallly also apply to code
generated from it.

This special cases `@license` comments, as Closure disregards directives
in comments containing `@license`.

Tobias Bosch edd5f5a333 perf(compiler): make the creation of `ts.Program` faster. (#19275)
We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.

This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.

This commit also:
- has a minor side effect on how we generate shared stylesheets:
  - previously every import in a stylesheet would generate a new
    `.ngstyles.ts` file.
  - now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
  This was required as we need to be able to determine the program files
  without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
  optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.
