vo_opengl: refactor how framebuffer depth is passed from backends

Store the determined framebuffer depth in struct GL instead of
MPGLContext. This means gl_video_set_output_depth() can be removed, and
also justifies adding new fields describing framebuffer/backend
properties to struct GL instead of having to add more functions just to
shovel the information around.

Keep in mind that mpgl_load_functions() will wipe struct GL, so the
new fields must be set before calling it.
