Alex Barney 9cb57fb4bb Adjust naming conventions for Ryujinx and ChocolArm64 projects (#484)
* Change naming convention for Ryujinx project

* Change naming convention for ChocolArm64 project

* Fix NaN

* Remove unneeded this. from Ryujinx project

* Adjust naming from new PRs

* Name changes based on feedback

* How did this get removed?

* Rebasing fix

* Change FP enum case

* Remove prefix from ChocolArm64 classes - Part 1

* Remove prefix from ChocolArm64 classes - Part 2

* Fix alignment from last commit's renaming

* Rename namespaces

* Rename stragglers
