vo_opengl, vo_opengl_cb: better hwdec interop backend selection

Introduce the --opengl-hwdec-interop option, which replaces
--hwdec-preload. The new option allows explicit selection of the interop
backend.

This is relatively complex, and I would have preferred not to add this,
but it's probably useful to debug certain problems. In exchange, the
"new" option documents that pretty much any but the simplest use of it
will not be forward compatible.
