02220b88fc avcodec/thread: Don't use ThreadFrame when unnecessary
The majority of frame-threaded decoders (mainly the intra-only)
need exactly one part of ThreadFrame: The AVFrame. They don't
need the owners nor the progress, yet they had to use it because
ff_thread_(get|release)_buffer() requires it.

This commit changes this and makes these functions work with ordinary
AVFrames; the decoders that need the extra fields for progress
use ff_thread_(get|release)_ext_buffer() which work exactly
as ff_thread_(get|release)_buffer() used to do.

This also avoids some unnecessary allocations of progress AVBuffers,
namely for H.264 and HEVC film grain frames: These frames are not
used for synchronization and therefore don't need a ThreadFrame.

Also move the ThreadFrame structure as well as ff_thread_ref_frame()
to threadframe.h, the header for frame-threaded decoders with
inter-frame dependencies.

e4c3ec3e00 Revert "avcodec/nvdec_av1: fix setting film grain parameters for frames with update_grain == 0"
This reverts commit f9eec6298387fe72cd8035ff45276cfc3da784a8.

This does not effectively cover all cases. The values for some frames need
to be inferred by the decoder.

f9eec62983 avcodec/nvdec_av1: fix setting film grain parameters for frames with update_grain == 0
The spec in section 6.8.20 states the parameters should be loaded from a
reference frame indexed by film_grain_params_ref_idx.
