fix[h264d_parser]: Fix pps parsing issue

Browse source 
Platform: General

Error case:
The source don't have the second_chroma_qp_index_offset

Solution:
The base line profile, Main profile, and Extended profile do not
support transform_8x8_mode_flag, pic_scaling_matrix_present_flag,
and second_chroma_qp_index_offset, so it is not parsed in these
cases.
