libs: va: Move the VA common logic as a lib.
...
The VA acceleration now has more usages in linux-like platforms,
such as the MSDK. The different plugins based on the VA acceleration
need to share some common logic and types. We now move the display
related functions and types into a common va lib.

gst: don't use volatile to mean atomic
...
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead. GCC 11 has started warning about using volatile
with atomic operations.

va: Fix a latent race condition in vabasedec.
...
The vabasedec's display and decoder are created/destroyed between
the gst_va_base_dec_open/close pair. All the data and event handling
functions are between this pair and so the accessing to these pointers
are safe. But the query function can be called anytime. So we need to:
1. Make these pointers operation in open/close and query atomic.
2. Hold an extra ref during query function to avoid it destroyed.

va: utils: use GstObject for GstVaDisplay in context
...
Thus application could fetch the GstVaDisplay through the sync bus
without knowning the specific implementation, and sharing it or
extract properties.

Add all the machinery to instanciate VA display through GstContext,
thus all va elements can share the same display and the user can set
a custom one.
