[SPARC] Remove the UT699 errata workarounds (#237953)
They do not cover all necessary workarounds and are not documented
and unlikely to be used. UT699 has been succeeded by UT699E/UT700,
so even if adding the missing workarounds they are unlikely to be used.
The workaround for AT697F could be made more efficient, but it looks
correct. Fold the pass into the errata workaround pass.
