7871144cf8 avcodec/av1_vaapi: setting 2 output surface for film grain 
VAAPI needs 2 output surface for film grain frame. One used for
reference and the other used for applying film grain and pushing
to downstream.

53403158cc avcodec/vaapi: increase av1 decode pool size 
For film grain clip, vaapi_av1 decoder will cache additional 8
surfaces that will be used to store frames which apply film grain.
So increase the pool size by plus 8 to avoid leak of surface.

4e7a7d75e3 avcodec/dxva2_av1: fix global motion params 
Defined in spec 5.9.24/5.9.25. Since function void
global_motion_params(AV1DecContext *s) already updates
gm type/params, the wminvalid parameter only need to get
the value from cur_frame.gm_invalid.

e7ff5722b1 cbs_av1: fix incorrect data type 
Since order_hint_bits_minus_1 range is 0~7, cur_frame_hint can be
most 128. And similar return value for cbs_av1_get_relative_dist.
So if plus them and use int8_t for the result may lose its precision.

3cc3f5de2a avcodec/hevcdec: apply H.274 film grain 
Similar in spirit and design to 66845cffc3, but slightly simpler due
to the lack of interlaced frames in HEVC. See that commit for more
details.

For the seed value, since no specification for this appears to exist, I
semi-arbitrarily decided to base it off the POC id alone, since there's
no analog of the idr_pic_id in HEVC's I-frames. This design is stable
across remuxes and seeks, but changes for adjacent frames with a period
that's typically long enough not to be noticeable, which makes it
satisfy all of the requirements that a film grain seed should have.

Tested with and without threading, using a patch to insert film grain
metadata artificially (for lack of real files containing film grain).
