arturovt 1e3999ec36 refactor(core): replace Optional/SkipSelf deps with inject() flags (#63386)
This commit updates provider definitions that relied on the `deps` array
with `new Optional()` and `new SkipSelf()` to instead use the modern
`inject(..., { optional: true, skipSelf: true })` API.

Previously:
  deps: [[KeyValueDiffers, new SkipSelf(), new Optional()]]

Now:
  const parent = inject(KeyValueDiffers, { optional: true, skipSelf: true });

**Bundle size reduction**: `Optional` and `SkipSelf` are runtime values
created by `makeParamDecorator()`. Even in production builds, esbuild
and other bundlers must keep their factory code because they are
referenced with `new Optional()` / `new SkipSelf()`. With `inject()`,
those classes are no longer referenced, allowing them and the
`makeParamDecorator` scaffolding to be tree-shaken when unused.

As a result, production bundles can drop both `Optional`, `SkipSelf`, and
their supporting factory code when not used elsewhere, reducing code size
while keeping the same behavior.
