video/out: remove an unused parameter

This parameter has been unused for years (the last flag was removed in
commit d658b115). Get rid of it.

This affects the general VO API, as well as the vo_opengl backend API,
so it touches a lot of files.

The VOFLAGs are still used to control OpenGL context creation, so move
them to the OpenGL backend code.
