Reviewed by Eric Carlson.
We were using the SPS sps_max_num_reorder_pics to compute the reorder window
size.
But it appears from testing and from Chrome source code that we should instead
use the VPS vps_max_num_reorder_pics.
We should probably get the VPS from PPS -> SPS -> VPS chain but for now, we use
the first VPS available.
We add VPS parsing up to vps_max_num_reorder_pics.
We make use of it for computing the reorder window size for both HVCC and
AnnexB cases.
Covered by LayoutTests/webrtc/h265.html and LayoutTests/http/tests/webcodecs/
HEVC tests.
