drm/xe/dg2: Drop pre-production workarounds

Pre-production hardware is anything before C0 (for DG2-G10), before B1
(for DG2-G11), or before A1 (for DG2-G12).  Workarounds specific to such
hardware was already removed from i915 in commit eaeb4b361452
("drm/i915/dg2: Drop pre-production GT workarounds") and there's even
less value keeping these around in the Xe driver.

v2:
 - Drop Wa_14011441408 from xe_mocs.c.  (Gustavo)
 - Drop Wa_14010648519, Wa_14010198302, and Wa_1608949956 which were
   mis-implemented; they were only supposed to apply to early steppings
   of DG2-G10, but were being applied unconditionally on all DG2.
   (Gustavo)
 - Drop reference to Wa_16011620976; the implementation stays because it
   still matches Wa_22015475538.  (Gustavo)
