cogl/driver: Move various texture functions to TextureDriverGL
As they are now shared between GL3 and GLES3 texture driver, there is no need anymore for having them in a separate header and included. Cleanup the names of the functions while doing so. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4163>
