pango: basetextoverlay: handle video/x-raw(ANY) if downstream supports the
GstVideoOverlayCompositionMeta API

Here is a work in progress using the caps query with caps features. It seems to
work fine in the upstream -> downstream direction however i'm wondering how we
should handle the downstream -> upstream case since at some point we don't know
what we really support.

My thoughts about it would be to somehow keep track of what we support during
the caps query in the downstream -> upstream direction.

Just filtering using the caps template feels wrong to me.

Comments welcome.
