Alex Rickabaugh fa52b6e906 feat(core): options object to supersede bit flags for inject() (#46649)
`inject()` originated as a private API and was made public to support
`InjectionToken` factories in Ivy. For code-size and performance reasons,
when we code generate `inject()` calls we use a bit field to indicate the
various injection modes (optional, skip-self, etc). However, this doesn't
make for a very nice public API.

This commit introduces an alternative object-based API for options. All 4
flags are supported as `boolean` fields on an options object, and converted
to bit flags internally. If TypeScript can prove that `optional` injection
is not requested, it can narrow the return type and remove the `null` type.

DEPRECATED:

The bit field signature of `inject()` has been deprecated, in favor of the
new options object. Correspondingly, `InjectFlags` is deprecated as well.
