Fixed issue with kvz_go_rice_par_abs where passing a unsigned argument caused MIN function to return wrong value. Modified coefficient coding to match VTM 5.0. Some issues still remain.

Minor fixes to header writing. Added contexts for multi_ref_line and BDPCM. Functions added for writing both in bitstream, but they are both disabled for now.

Fix transform skip for inter
...
The transform skip flag in cu_info_t was stored under the intra
substruct even though transform skip can be used for inter as well. This
caused bitstream errors. Fixed by moving the flag out of the substruct.

Reduce copying in kvz_get_coeff_cost

not the whole encoder state.
Other threads could be simultaneously using the other parts of the
encoder state. Only copying the CABAC fixes a TSan data race warning.

Set inter transform depth to zero
...
Sets max_transform_hierarchy_depth_inter to 0 in SPS. This saves some
bits because split_transform_flag does not need to be coded for inter
blocks.
When SMP and AMP blocks are enabled the depth is set to 1 instead.
Otherwise inter split flag would default to 1 for SMP and AMP blocks,
resulting in an unnecessary transform split.
