0e782661d6 cbs_h264: Fix overflow in shifts 
The type of the result of a shift operation is unaffected by the type of
the right operand, so some existing code overflows with undefined behaviour
when the element length is 32.  Add a helper macro to calculate the maximum
value correctly and then use it everywhere this pattern appears.

  cbs_h264: Add hack for pic_timing with no active SPS

Partially fixes #6896 - the sample stream from that ticket now works, but
more obscure cases can still fail.

7157d95926 cbs_h264: Move slice_group_id array out of PPS structure 
It's very large, and is only used in some FMO streams.

If there is exactly one possible SPS but it is not yet active then just
assume that it should be the active one.
