Disable PlatformDisplayDefaultTest.EventDispatch.

This test worked yesterday on the bots, but failed today. There doesn't seem to
have been any change in the interim.

 Issue 733332  has been merged into this issue.

It still works for me when I run it as part of services_unittests, but fails if I run with --gtest_filter. The code calling InitializeForGPU in run_all_service_tests.cc isn't [always] executed on PlatformDisplayDefaultTest.EventDispatch's process when it runs as part of the full suite. 

One way to fix this could be to only do OzonePlatform initialization for the tests that need it and tear it down at the end. Or perhaps break up services_unittests into multiple binaries.

mash: Implement basic display mirroring in the Window Service.

Add PlatformDisplayMirror to represent mirroring destination displays.
Have ws::DisplayManager own and manage the mirrors as directed by Ash.
Add DisplayManager::OnFirstSurfaceActivation helper to notify mirrors.
Add FrameGenerator::scale_and_center_ behavior for mirror displays.

Minor cleanup and invert a broken conditional in ws::Display.

Fix a PlatformDisplay test, add a CreatePlatformWindow helper.
Remove an OzonePlatform accessor, I'll fix the test separately.

TODO: Get Mash cursor mirroring enabled (via cursor compositing?)

Fix Stub PlatformWindow creation pattern for testing.

Avoid overriding the OzonePlatform instance with a test subclass.
Instead, have PlatformDisplayDefault make StubWindows for invalid ids.
