From: Linjie Fu <linjie.fu@intel.com>
Use GPB frames to replace regular P frames if backend driver does not
support it.
- GPB:
Generalized P and B picture. P frames replaced by B frames with
forward-predict only, L0 == L1. Normal B frames still have 2
different ref_lists and allow bi-prediction

update:
1. Fix hevc encode fail on ICL platform.
2. Optimize debug log message.

The block size can be dependent on the profile and entrypoint selected.
It defaults to 16x16, with codecs able to override this choice with their
own function.

max_14bit_constraint_flag should be set if the bit depth is not greater than
14 (currently always true).
one_picture_only_flag should not be set because we don't support the still
picture profiles.
general_profile_compatibility_flag should be set according to general_profile_idc
instead of bit depth.
