Added run-time switching between OpenGL & ANGLE in SampleApp

This patch allows SampleApp to switch to ANGLE via the usual left-arrow mechanism. There is still an issue where ANGLE doesn't clean up correctly (so one cannot switch back to OpenGL from ANGLE).

Did you test that hitting \ still works (uses the null device)?

Yes - I also ensured that toggling away from the null device also worked.

It looks like we missed src/views/mac/SkOSWindow_Mac.mm. I have some vague
memory that SkOSWindow_mac.cpp is the old Carbon file and SkOSWindow_Mac.mm is
the new Cocoa implementation developed by Yang. If that's right we should send
the former to its final resting place.
