drm/amd/display: Add dml2_core_dcn6_calcs function pointer table

Browse source 
[Why]
DCN6 core mode support/programming call DCN5 and DCN6 calcs
functions directly by name. The calcs layer needs one seam the
funcs layer can go through instead of hardcoding a generation.

[How]
Add union dml2_core_calcs holding one function pointer table
per generation, plus a calcs field on dml2_core_instance and on
the mode support/programming contexts.
Add dml2_core_dcn6_calcs.c/.h defining struct
dml2_core_dcn6_calcs, a flat table covering every DCN6 calcs
function and every DCN5 calcs function DCN6 reuses, and
dml2_core_dcn6_calcs_init() to populate it.
Call dml2_core_dcn6_calcs_init() from
dml2_core_dcn6_funcs_initialize().
