drm/xe: Consolidate workaround entries for Wa_14019877138

Wa_14019877138 applies to all graphics versions from 12.55 through 20.04
(inclusive) that have a render engine.  Consolidate the RTP entries into
a single range-based entry.

Note that the DG2 entry for this workaround was missing an
ENGINE_CLASS(RENDER) rule; that mistake is fixed by this consolidation.
