[roll] Roll fuchsia [test-ui-stack] Implement minimal graphical presenter in scene provider

The current implementation has some substantial limitations:

1. It ignores annotations.
2. It doesn't support ViewController or AnnotationController behavior;
   it will only hold the channels open, if handles are supplied.
3. It is incompatible with geometry observation. There's no way to
   return the client root view's ViewRef to the client, so the client
   can't easily identify its view in view tree snapshots. We have a
   proposal out to resolve this issue, but we likely won't land the fix
   for several weeks. In the interim, some use cases, e.g. chrome's
   frame_impl_browsertest, may not need geometry obervation, so it's worth
   offering GraphicalPresenter by itself.

Test: ran pointerinjector-config-test using GraphicalPresenter
