Delete old Ozone surface creation API.

This CL deletes the remainder of the old Ozone surface API. All Ozone
platforms have been switched over to the new API and directly create
GLSurfaces.

Remove SurfaceOzoneEGL, GLSurfaceOzoneEGL and some helper methods. The
SwapCompletionCallback typedef from SurfaceOzoneEGL is moved to it's own
file so it can still be used.

This essentially finishes the refactor in the associated bug.
