commit 036945276e54bd6d98d3e51ccfec21c56dc80b61

Add GLOzone interface.

Move the Ozone platform GL implementation code into a single interface.
Right now the code to implement EGL for an Ozone platform is located
part in //ui/gl/init and part in SurfaceFactoryOzone implementation.

The current approach exposes EGL specific concepts in the shared Ozone
code. This works fine currently because EGL is relatively platform
agnostic. This gets much messier for GLX because it is not platform
agnostic.

Move the existing shared EGL code into an abstract class GLOzoneGL that
implements GLOzone. Each Ozone platform can then finish the
implementation. This has a nice side effect that SurfaceFactoryOzone no
longer has to expose EGL concepts.

Only the Ozone X11 platform is updated initially. The GBM, cast and
wayland Ozone platforms will need to be updated to use the new interface
in a subsequent CL.

Implement GLX for Ozone X11.

This CL adds GLX support to the Ozone X11 platform. Ozone X11 will
attempt to use GLX by default.

It reuses the existing GLX GLSurface and GLContext. Changes to
NativeViewSurfaceGLX are necessary as it handles Expose events from the
PlatformEventSource. The class is split into an abstract base class with
two small event handling implementations for USE_X11 and USE_OZONE.

Ozone caca: Fix segfault during GPU initialization

After https://codereview.chromium.org/2270463002,
gl::init::GetAllowedGLImplementations assumes GetSurfaceFactoryOzone to
be non-null on the GPU side. The remaining Ozone platform violating
this assumption is addressed in this CL.

Fix the MessageLoop type in case more than one ozone platform is built

One of the premises of Ozone is that one can trigger
a backend at runtime. For example, if one has

  ozone_platform_x11=true
  ozone_platform_wayland=true

.. in the GN args, it should be able to launch either backend
by passing --ozone-platform=x11|wayland. This enforces no compile
time branches where possible.
In [1], a OZONE_X11 define was added, and slightly breaks that
premise.

This CL fixes it by:

- making OzonePlatform::CreateInstance public (and renaming it to
  ::EnsureInstance). This allows the creation of the OzonePlatform
  instance without doing any actual initialization.

- Adding a OzonePlatform::GetMessageLoopTypeForGpu virtual method,
  which returns the MessageLoop type required for the GPU depending
  on the Ozone platform selected at runtime.
