Deleted WebGLES2ContextImpl and references to it and WebGLES2Context.

This is a prerequisite to deletion of GLES2Context and WebGLES2Context
from the WebKit repository. There is a TODO, to which the video stack
team has agreed, to switch over the experimental hardware-accelerated
video decoding from WebGLES2Context to WebGraphicsContext3D.

The remaining vestige, removal of the implementation of
WebGraphicsContext3D::initialize(Attributes, WebView*), will occur
once the associated method is deleted from WebKit.

Built and tested 3D CSS and WebGL content on Mac OS X and Windows.

BUG=52863
TEST=none
