drm/xe/wa_oob: Consolidate some OOB rules

Given the new policy of allowing graphics/media IP ranges to extend over
unused IP versions, we can consolidate some of the OOB workaround rules
and simplify the table.  If new IP variants eventually show up that use
these unused versions (e.g., media version 30.01, graphics versions
20.03 / 30.02, etc.), and if an existing workaround does not extend to
that new intermediate version, the ranges will be split back apart as
part of the enablement work for that new IP version.
