media: iris: Add internal buffer calculation for AV1 decoder

Browse source

Implement internal buffer count and size calculations for AV1 decoder
for all the buffer types required by the AV1 decoder, including BIN,
COMV, PERSIST, LINE, and PARTIAL.

This ensures the hardware decoder has properly allocated memory for AV1
decoding operations, enabling correct AV1 video playback.
