drm/i915/xelpd: Add rc_qp_table for rcparams calculation 

Add the qp table for 444 formats, for 8bpc, 10bpc and 12bpc, as given by
the VESA C model for DSC 1.1

v2:
 - Add include guard to header (Jani)
 - Move the big tables to a .c file (Chris, Jani, Lucas)
v3:
 - Make tables 'static const' and add lookup functions to index into
   them.  (Jani)
v3.1:
 - Include missing .h file.
