VT-x: extend LBR Broadwell errata coverage

VT-x: extend LBR Broadwell errata coverage

For lbr_tsx_fixup_check() simply name a few more specific erratum
numbers.

For bdf93_fixup_check(), however, more models are affected. Oddly enough
despite being the same model and stepping, the erratum is listed for
Xeon E3 but not its Core counterpart. Apply the workaround uniformly,
and also for Xeon D, which only has the LBR-from one listed in its spec
update.

Seeing this broader applicability, rename anything BDF93-related to more
generic names.
