When setting `"useDefineForClassFields": false`, static fields are compiled within a block that relies on the `this` context. This output makes it more difficult for bundlers to treeshake and eliminate unused code.

We have removed the `esm2022` directory from the generated package, as it was unused and contributed 7.7 MB to `@angular/core`. The `ng_package` rule still passes `esm2022` to the packager to perform `analyzeFileAndEnsureNoCrossImports`.
A moment of reflection:
You've always been there, full of potential, yet never called upon. Now, we bid you farewell.

This commit integrates the JSA contract binary into the NPM package and ensures its accessibility by including it in the package exports. This adjustment is essential for enabling Angular CLI to effectively access and inject the script. Additionally, sourcemaps are removed from the minified bundle to prevent their inclusion in the HTML page.

Updates the repo to support TypeScript 5.3 and resolve any issues. Fixes include:
* Updating usages of TS compiler APIs to match their new signatures.
* In TS 5.3 negative numbers are represented as `PrefixUnaryExpression` instead of `NumericExpression`. These changes update all usages to account for it since passing a negative number into the old APIs results in a runtime error.

This commit reorganizes the Angular code a bit, and moves signals into a
newly defined `@angular/core/primitives` location. This will be used inside
g3 to allow non-Angular targets to depend on the signals core without
incurring a dependency on the whole framework.

Enables the new `@` block syntax by default by removing the `enabledBlockTypes` flags. There are still some internal flags that allow special use cases to opt out of the block syntax, like during XML parsing and when compiling older libraries (see #51979).

Reworks the `setClassMetadata` calls to generate arrow functions instead of full anonymous function declarations. While this won't have an effect on production bundle sizes, it's easier to read and it should lead to small parsing time gains in dev mode.

We control most flags via Starlark and therefore limit configuration
options via `tsconfig` to a minimum. We do not intend to support the
enabled block types option via Starlark, so this commit allows for
the option to be picked up.
(This is useful for benchmarking the new control flow blocks).

BREAKING CHANGE: Node.js v16 support has been removed and the minimum support version has been bumped to 18.13.0.
Node.js v16 is planned to be End-of-Life on 2023-09-11. Angular will stop supporting Node.js v16 in Angular v17. For Node.js release schedule details, please see: https://github.com/nodejs/release#release-schedule

We were collecting all ES2022 files from entry-points (including
transitive files). Those are later on combined and filtered so that
we know which files to copy over to the package. There was no
deduping here. This did not have an effect, but could be a source
of slowness in `ng_package` and also breaks validation checks which
could show same errors multiple times for the same file.
PR Close#51500
Introduces a check into `ng_package` that will ensure that there are no
cross entry-point or cross-package relative imports that would end up
contributing to duplicate code. Not only would duplicate code result in
size increases, but also it could cause subtle hard-to-debug bugs,
especially when cross imports rely on e.g. singletons. Like for example
the deps tracker that is used in angular/core but also in
angular/core/testing.

`tsickle` is not used in any code paths in 3P and we can remove
this complexity. The `tsickle` npm package has not been released
in a while and we are risking breakages with e.g. future TypeScript
versions.
Note that the `ng_module` rule was updated to not emit through
tsickle at all. The tsickle in 1P is done directly by `tsc_wrapped`
and our code path in `compiler-cli` is not needed at all.

In local mode compilation the TS semantic check issues tons of diagnostics due to the fact that the file dependencies (.d.ts files) are not available in the program. So it needs to be disabled.
This commit should not cause any issue for the exsiting projects as it just removes a diagnostic in the local compilation mode.

This commit updates the minimum supported Node version across packages from 16.13.0 -> 16.14.0 to ensure compatibility with dependencies.

This commit adds the infrastructure for `@angular/core/rxjs-interop`, a new
core entrypoint which provides bidirectional interoperability between
Angular's built-in reactivity system of synchronous signals, and the RxJS
`Observable` abstraction.
The new entrypoint is set up as an empty shell in this commit, with its
implementation to follow in a followup.
