[APX] Prohibit SHA/KEYLOCKER usage of EGPR when APX enabled

[APX] Prohibit SHA/KEYLOCKER usage of EGPR when APX enabled

The latest APX spec announced removal of SHA/KEYLOCKER evex promotion,
which means the SHA/KEYLOCKER insn does not support EGPR when APX
enabled. Update the corresponding constraints to their EGPR-disabled
counterparts.
