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 * Fix alignment * Rename OpCode class * Missed a few * Adjust alignment
