Alan Agius fc643c9044 build: adopt moduleResolution: "bundler" (#64125)
This commit updates the TypeScript configuration across the project to use `moduleResolution: "bundler"`. This modernizes our module resolution strategy to align with current TypeScript best practices and bundler behaviors.

The following changes are included:
- Updated `tsconfig.json` files to set `moduleResolution` to `"bundler"`.
- Updated the `rules_angular` bazel dependency to a version compatible with these changes.
- Adjusted related test files and golden files to reflect the new module resolution strategy.

ivanwonder eeeaadc7e9 fix(language-service): Support to resolve the re-export component. (#62585)
In the context of TypeScript (TS), a re-exported symbol is considered a distinct symbol.
This means that a developer can choose to import either the re-exported symbol or
the original symbol. However, in the context of Angular, the re-exported symbol
is treated as the same component because it uses the same selector.

This pull request will utilize the most recent re-export component file to
resolve the module specifier.

Andrew Scott 812463c563 fix(compiler-cli): Ignore diagnostics on ngTemplateContextGuard lines in TCB (#63054)
Deprecated diagnostics can appear on the context guard becaues the
directive itself may be deprecated.

For example, context guards look like `if (i1.NgForOf.ngTemplateContextGuard(_t8, _t9) /*331,378*/) {...}`
and typescript will report the deprecation on the whole element, from
start to end tag, because the span for that node includes it.

ivanwonder b78de31c94 refactor(language-service): handle the undefined value of a symbol for a type (#63002)
using the `getSymbol` instead of the `type.symbol`, for the primitive type,
the `type.symbol` returns the `undefined` value. The return type of `getSymbol`
includes `undefined`, while `type.symbol` does not.

For example:

```ts
class BarComponent {
   /**
   * @deprecated
   */
  name = ""
}
```

The type of `name` is `string`, the `type.symbol` for the `string`
returns `undefined` here.

Paul Gschwendtner 810b0a7e5c refactor: add explicit types for exports relying on inferred call return type (#61312)
As part of the Bazel toolchain migration we noticed that implicit types
generated by the TypeScript compiler sometimes end up referencing types
from other packages (i.e. cross-package imports).

These imports currently work just because the Bazel `ts_library` and
`ng_module` rules automatically inserted a `<amd-module
name="@angular/x" />` into `.d.ts` of packages. This helped TS figure
out how to import a given file. Notably this is custom logic that is not
occuring in vanilla TS or Angular compilations—so we will drop this
magic as part of the toolchain cleanup!

To improve code quality and keep the existing behavior working, we are
doing the following:

- adding a lint rule that reduces the risk of such imports breaking. The
  failure scenario without the rule is that API goldens show unexpected
  diffs, and types might be duplicated in a different package!

- keeping the `<amd-module` headers, but we manually insert them into
  the package entry-points. This should ensure we don't regress
  anywhere; while we also improved general safety around this above.

Long-term, isolated declarations or a lint rule from eslint-typescript
can make this even more robust.

Paul Gschwendtner e0ff321433 build: prepare testing infrastructure for code splitting of core package (#60487)
When we switch to relative imports, shared `.d.ts` chunks can be
generated.

We need to also pull these into our mock virtual FS testing
environments. Notably this does not cause a test slow-down because we
are talking about very few extra `.d.ts` chunk files. In our experiments
before, with no dts bundling, we saw test time increase from e.g.
20seconds to 100seconds. The 20s are still the same locally!

In addition, since code for definitions can now reside in shared `.d.ts`
chunks, the language service tests need to be adjusted in cases where
they assert for code definition locations in `@angular/core`. A new
helper prepares for more code to be moved into arbitrary `.d.ts` files;
we should simply assert the definition comes out of
`node_modules/@angular/core`.

Paul Gschwendtner 4fa5d18e5a feat(bazel): support bundling .d.ts with code splitting (#60321)
Instead of relying on Microsoft's API extractor for `d.ts` bundling,
we are switching to Rollup-based `.d.ts` bundling.

This allows us to support code spliting, even for `.d.ts` files,
allowing for relative imports to be used between entry-points, without
ending up duplicating `.d.ts` definitions in two files. This would otherwise cause
problems with assignability of types.

It also nicely integrates into our existing rollup configuration, and
overall simplifies the `ng_package` rule even further!

Notably `tsup` also uses this rollup plugin, and it seems to work well.
Keep in mind that Microsoft's API extractor is pretty hard to integrate,
caused many problems in the past, and isn't capable of code splitting.
This aligns our d.ts bundling with the .mjs bundling (great alignment).
