h264parser: Expose all parsed flags of slice header

Browse source 
Add num_ref_idx_active_override_flag and sp_for_switch_flag to
member of GstH264SliceHdr. No reason to hiding them and
some decoder implementations (e.g., DXVA) rely on externally parsed header
data which can be provided by h264parser.
