cogl: consolidate _create_context_driver + _features_init

Browse Source 
This moves the functionality of _cogl_create_context_driver from
driver/{gl,gles}/cogl-context-driver-{gl,gles}.c into
driver/{gl,gles}/cogl-{gl,gles}.c as a static function called
initialize_context_driver.

cogl-context-driver-{gl,gles}.[ch] have now been removed.
