2886eab3c4 alphacombine: Fix for early allocation queries
When using playbin3, it seems that the alpha decode is always first to
push caps and run an allocation query. As the format change from sink
and alpha were not synchronized, the allocation query could endup
being run before the caps are pushed. That may lead to failing query,
which makes the decoder thinks there is no GstVideoMeta downstream and
most likely CPU copy the frame.

This patch implements a format cookie to track and synchronize the
format changes on both pads fixing the racy performance issue.

91b7a9497b vp9alphadecodebin: Fix auto-pluging v4l2slvp9dec
This adds the alignment field to the template caps. Without this field
set, the auto-plugger will see fixed caps and will use
gst_caps_is_subset() against the caps produced by the parser. This is a
challenge for all cases where a parser can do conversion. This is fixed
by adding alignment field, which makes the auto-pluggers do an
intersection of the caps as it gets unfixed caps after intersection now.

bc358e5827 alphacombine: use the same allocation query data for both decoders
This allows downstream elements to set allocation query parameters for both
decoders, which should be always the same.
