This adds `generate_api_docs` targets to all of the packages for which we publish api reference docs. One known issue here is that any type information that comes from another package (e.g. router depending on core) currently resolve to `any` because the other sources are not available in the program. This can be tackled in a follow-up commit.
This commit also updates the install patch for `@angular/build-tools` to use the local version of compiler-cli.

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.
