Cpu: Implement VCVT (between floating-point and fixed-point) instruction (#5343)1.1.932
* cpu: Implement VCVT (between floating-point and fixed-point) instruction
Rebase, fix and superseed of https://github.com/Ryujinx/Ryujinx/pull/2915
(Since I only have little CPU knowledge, I hope I have done everything good)
* Update Ptc.cs
* Fix wrong cast
* Rename tests
* Addresses feedback
