Subject: Added Generic Math to BitUtils (#3929)

* Generic Math Update

Updated Several functions in Ryujinx.Common/Utilities/BitUtils to use generic math

* Updated BitUtil calls

* Removed Whitespace

* Switched decrement

* Fixed changed method calls.

The method calls were originally changed on accident due to me relying too much on intellisense doing stuff for me

* Update Ryujinx.Common/Utilities/BitUtils.cs
