cogl: Move various vfuncs from DriverVtable to TextureDriver

Browse Source 
As they make more sense there. Maybe we could have a common
OpenGLTextureDriver
that would share the common texture_2d_* vfuncs but that can be done
later.

By moving those vfuncs to the TextureDriver, we can get rid of the
texutre_2d
nop driver implementations.
