[LibWebRTC][WPE][GTK] Enable vp9 and NO_MAIN_THREAD_WRAPPING

[Philippe Normand]

NO_MAIN_THREAD_WRAPPING prevents creating socket server in Web Process. Also I see no reason preventing us to enable H.265 and VP9, unless I missed something?

[Philippe Normand]

Actually I'm not sure H.265 makes much sense for us, VP9 should cover most cases nowadays.

I think we should at least warn here as well.

[Philippe Normand]

A glib warning is already raised when linking fails.

In fact this is the only place where we check a _link_many return value. I wonder if it makes much sense anyway. :)
