[chromium] Avoid calling getUniformLocation??() in the compositor startup

Source/Platform:

Adding an entry point for bindUniformLocationCHROMIUM.

* chromium/public/WebGraphicsContext3D.h:
(WebGraphicsContext3D):
(WebKit::WebGraphicsContext3D::bindUniformLocationCHROMIUM):

Source/WebCore:

This change allows chrome compositor to bind uniform locations instead of querying
them from the graphics context by using GL_CHROMIUM_bind_uniform_location.

The extention itself is tested in chromium and the change in webkit simply adds
plumbing to allow its usage. Existing pixel tests would be able to verify proper behaviour.
