gst-va-intel: add conditional vaapi implementation

Use different versions of vaapi interface implementaion depending on
what a machine specifies.  The default if no MACHINE_FEATURE is
specified is gstreamer-vaapi.  Other machines may need a different
implementation e.g. a machine using emgd would specify
'gst-va-mixvideo' in its MACHINE_FEATURES in order to have the
implementation satisfied by emgd instead of gstreamer-vaapi, which
this also implements.
