From: Linjie Fu <linjie.fu@intel.com>
1. Add extension syntax according to 7.3.2.2.3/7.3.2.3.3 in T-REC-H.265-201911.
2. Keep using parsed PPS when bitstream overread for compatibility. For
example, the clip PS_A_VIDYO_3.bit in FATE test has incomplete extension
syntax which will be overread and un-decodable if without this change.
3. Format brace in pps_range_extensions().

According to 7.3.6.1, use_integer_mv_flag should be parsed if
motion_vector_resolution_control_idc equals to 2. If not present, it
equals to motion_vector_resolution_control_idc.

Screen Content Coding allows non-intra slice in an IRAP frame which can
reference the frame itself, and would mark the current decoded picture
as "used for long-term reference", no matter TwoVersionsOfCurrDecPicFlag(8.1.3),
hence some previous restricts are not suitable any more.
Constructe RefPicListTemp and RefPicList according to 8-8/9/10. Disable
slice decoding for SCC profile to avoid unexpected error in hevc native
decoder and patch welcome.

chroma_format_idc from 0, 1 or 3, hence both 420 and 444 are
