Revert 247793 "Ensure GL initialization only happens once, and p..."

due to new static initializers in gl_bindings_autogen_gl.cc

> Ensure GL initialization only happens once, and provide common init path
> 
> Currently tests initialize GL by calling into methods that should be
> internal to the gl bindings code. Instead, everyone should go through
> GLSurface::InitializeOneOff.
> 
> Also GLSurface::InitializeOneOff early outs if it was already called,
> leading to a pattern of initializing GL all over the place just in case
> and not having a clear idea of where it should be set up. Instead, DCHECK
> that it is not called more than once, and move calls to this method to
> be during process startup for unit test suites instead of mid-test.
> 
> This adds two test variants of InitializeOneOff for tests to call, that
> set up OSMesa or Mock GL bindings, via GLSurface::InitializeOneOff.
