Now that Chromium's compositor has been switched over to use GraphicsContext3D for its rendering, the GLES2Context and WebGLES2Context abstractions need to be removed. Their presence is breaking the Windows multi-DLL build due to multiple inclusions of the command buffer client code and its thread-local variables.

From the ChangeLog:
Removed now-obsolete GLES2Context and WebGLES2Context classes, and dependency on command buffer client code from WebCore. Built and tested 3D CSS and WebGL content on Mac OS X to test.
