Implemented in IR the managed methods of the Saturating region ... (#3665)

* Implemented in IR the managed methods of the Saturating region ...

... of the SoftFallback class (the SatQ ones).

The need to natively manage the Fpcr and Fpsr system registers is still a fact.

Contributes to https://github.com/Ryujinx/Ryujinx/issues/2917 ; I will open another PR to implement in Intrinsics-branchless the methods of the Saturation region as well (the SatXXXToXXX ones).

All instructions involved have been tested locally in both release and debug modes, in both lowcq and highcq.

* Ptc.InternalVersion = 3665

* Addressed PR feedback.
