Pete Bacon Darwin 857dfaa1e7 refactor(core): remove the need for ɵɵinjectPipeChangeDetectorRef() (#41231)
This instruction was created to work around a problem with injecting a
`ChangeDetectorRef` into a pipe. See #31438. This fix required special
metadata for when the thing being injected was a `ChangeDetectorRef`.

Now this is handled by adding a flag `InjectorFlags.ForPipe` to the
`ɵɵdirectiveInject()` call, which avoids the need to special test_cases
`ChangeDetectorRef` in the generated code.
