82294fd665 vtdec: Fix caps criticals during negotiation
Calling gst_pad_peer_query_caps() without a filter can give us EMPTY caps, whereas all the code below
assumes that's not the case. Replacing query+intersect with a filtered query ensures we always get a subset
of the template caps back.

982c73dfdd vtdec: Ignore output loop errors in drain() if we're flushing
In an early non-linked scenario, this was causing a ton of criticals about the queue array,
because the output callback would still fire for leftover frames that were still being processed by VT
at the time the output loop stopped. This makes sure they're flushed correctly as well.

Also renames gst_vtdec_loop to gst_vtdec_output_loop for consistency with related functions.

112951ce55 vtdec: Fix a deadlock during ProRes playback
Sometimes a call to negotiate (and thus drain) can happen from the output loop
(via finish_frame()), which will tell VT to output all internal frames, but that won't succeed
if we happen to decide to wait for the queue to empty (because the loop is waiting for draining to finish and
will not make space in the queue!). This commit adds an override for the queue size limit if we're draining/flushing.

This bug could happen for any formats, but was especially obvious for ProRes, which has dpb_size of 0.

e79b308f82 vtdec: Fix deadlock when attempting to negotiate
This was wrongly calling the base class method, which unnecessairly took the stream lock, already taken by
handle_frame(). The drain() call in negotiate() would then wait for the output loop to pause, while that loop
is stuck waiting to take the stream lock, thus causing a deadlock.

85adc2daee vtdec: Handle output in separate thread
Moves outputting frames to a task on the source pad, bringing vtdec in line with vtenc.
This brings possible performance improvements thanks to decoupling queueing new frames from outputting processed ones.
The queue length is limited to `2*DBP` to prevent decoding too far ahead compared to what we're pushing downstream.

In the process we have changed the color value range from video-range
to full-range, which is probably what people want in the first place.

e2deebb103 vtdec: Fix not waiting for async frames when flushing
This was causing incorrect output when seeking, especially
when used with a multithreaded source like `videotestsrc n-threads=2`.
It should now correctly wait for frames still being processed by VT
while vtdec is flushing.

bb32532f60 applemedia: Disable 64RGBALE support on older macOS
The kCVPixelFormatType_64RGBALE enum is only available on macOS Big
Sur (11.3) and newer. We also cannot use that while configuring the
encoder or decoder on older macOS.

Define the symbol unconditionally, but only use it when we're running
on Big Sur with __builtin_available().

0f0e68080c applemedia: Add ProRes support to vtenc and vtdec
For vtdec, we continue to prefer NV12; else we pick whatever
downstream wants. In the special case where we're decoding 10-bit or
12-bit ProRes formats, we will prefer AYUV64.
