v4l2codecs: Detect missing M2M_HOLD_CAPTURE_BUF
...
Produce an error if we try to use the feature of holding capture buffer
but it is not supported by the driver. Ingoring this can lead to stalls
as the driver will run-out of capture buffer to decode into. This
affects slice decoders but also split-field interlaced decoding.

the forward probabilities in hardware hence does not need and
does not implement support for

v4l2codecs: gstv4l2decoder: set minimum sizeimage
...
Set minimum sizeimage such that there is enough space for any overhead
introduced by the codec.
Notably fix a vp9 issue in which a small image would not have a
bitstream buffer large enough to accomodate it.
