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.

2d6da02653 applemedia: Consolidate GstVideoFormat <-> CVPixelFormat conversion
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().

d05fcadf4e applemedia: Document vtenc / vtdec elements
Also preserve-alpha property should only be exposed on the
vtenc_prores element since h264 does not support transparency.

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.
