vo_gpu: update render options on runtime 

vo_gpu has a small set of options for ra_ctx that can be set. In
practice, runtime toggling doesn't matter for most of these as they have
no effect while a video is playing. However, changing the alpha option
during runtime can actually work depending on the backend used. mpv
already detected when one of these options changed, but it made no
attempt to update the options in the ra_ctx accordingly (likely because
nothing made any use of this information). Another related change is to
add an update_render_opts to the fns and allow invidiual backends to
(optionally) use it.
