Don't initialize GL again in AcceleratedSurface::Initialize()

Don't initialize GL again in AcceleratedSurface::Initialize()

GL is initialized in content::SupportsCoreAnimationPlugins() so
initializing it again hits DCHECKs and breaks things. Depend on
the initialization to occur in SupportsCoreAnimationPlugins()
only, and ensure that it only happens there once.

Eh, this isn't quite right. I think this will kill 3d in NPAPI plugins. We
lazy-init GLSurface on Mac in the renderer for NPAPI plugins in
content::SupportsCoreAnimationPlugins().

We can just make sure that SupportsCoreAnimationPlugins() only initializes
bindings once.

Uploaded new patch.
