GPU: Eliminate CB0 accesses when storage buffer accesses are resolved (#3847)
* Eliminate CB0 accesses

Still some work to do, decouple from hle?

* Forgot the important part somehow

* Fix and improve alignment test

* Address Feedback

* Remove some complexity when checking storage buffer alignment

* Update Ryujinx.Graphics.Shader/Translation/Optimizations/GlobalToStorage.cs
