Similar to Dav1dPicAllocator, this allocates from DMA-visible GPU memory. Especially useful on platforms that don't support arbitrary host pointer imports.
As an aside, also improve the handling of single-allocation AVFrames in general, which is a common-ish use case. As usual, some stupid gymnastics are performed to try and detect our mapped buffers when given arbitrary AVFrames.
Make plplay
use this, for testing purposes.
