  [PowerPC] Use `RegisterClassInfo::getRegPressureSetLimit` (#120383)

`RegisterClassInfo::getRegPressureSetLimit` is a wrapper of
`TargetRegisterInfo::getRegPressureSetLimit` with some logics to
adjust the limit by removing reserved registers.

It seems that we shouldn't use
`TargetRegisterInfo::getRegPressureSetLimit`
directly, just like the comment "This limit must be adjusted
dynamically for reserved registers" said.

Separate from https://github.com/llvm/llvm-project/pull/118787
