  [PowerPC] Enable using HwMode for instructions (#191051)

The HwMode is already used for operands representing an effective
address. It can also be used for general purpose registers but this is
not clear from the naming. This change

- introduces the hw-mode dependent register class `GxRC`, and the
associated register operands
- removes register class `ptr_rc_idx_by_hwmode`, and replaces the only
use with `gxrc`
 - uses the `EQV` instruction as an example how to use the new class
