va: misc fixes
va: allocator: log dmabuf and surface at pool push or pop
In order to keep track of the dmabuf fds and surfaces numbers log messages are
added at memory_release() (queue push) and prepare_buffer() (queue pop).
va: h265dec: fix HVC1 stream format name
va: basedec: refactor context query
Context query is handled either by source and sink queries. This patch
factors-out its handling in a common utility function.
va: filter: use a common GParamFlags definition
Instead of repeating the same code along gst_va_filter_install_properties()
va: h264dec: remove spurious if validation
The first if checks for caps, thus else doesn't need to recheck for the
opposite.
