cogl/gl: Move shared functions to shared file

Browse Source 
Cogl shares some GL functions between the GLES and the big
GL drivers. Namely, it shares _cogl_driver_gl_context_init
and _cogl_driver_gl_context_deinit between these two drivers.

The plot twist is: even though these functions are shared and
their prototypes are in cogl-util-gl-private.h, they're actually
implemented inside cogl-driver-gl.c, which is strictly only
about the big GL driver.

This is problematic when building Mutter on ARM v7, where we
need to disable OpenGL, but keep GLES enabled.

Fix this by moving the shared GL functions to a shared GL file.
