mesa: Treat glBindFramebuffer and glBindFramebufferEXT more correctly
Allow user-generated names for glBindFramebufferEXT on desktop GL. Disallow its use altogether for core profiles. Names bound with glBindFramebuffer in desktop OpenGL are still (incorrectly) shared across the share group instead of being per-context. This gets us a bit closer to being strictly conformant. v2: Disallow glBindFramebufferEXT in 3.1 by not installing it in the dispatch table. Suggested by Jordan.
