We've been experimenting with the DeepReadonly type that would make
signal values deeply read-only and prevent accidental changes without
going to the owner of data. What we've found out during the experiments
is that additional safety net has more drawbacks than benefits: it just
introduces too much friction to be practical for daily usage.

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.

This commit adds the basic sketch for the implementation of `fromObservable`
and `fromSignal`, the two basic primitives which form the RxJS interop layer
with signals.

This commit implements an RxJS operator `takeUntilDestroyed` which
terminates an Observable when the current context (component, directive,
etc) is destroyed. `takeUntilDestroyed` will inject the current `DestroyRef`
if none is provided, or use one provided as an argument.
