ARMeilleure: replace else-ifs with switch statements

[LukeWarnut]

This PR replaces several if/else if/else statements with switch statements across ARMeilleure. This should result in a very minor performance increase in some CPU/PPTC-related tasks.

I've tested several games with no issues, but further testing is welcome.

Great job! I’ll add some tests to check if there’s been any regression.

EDIT 2: I uploaded it again with h.264

Note

The problem is actually not the H.265, but the Microsoft Media Foundation (MF) CDM (Content Decryption Module) DRM
The video was likely recorded with a Microsoft tool instead of smth clean like OBS

It would be great to see this merged, but we're still waiting on the sparse jit pr, which hasn't yet been tested to Greem's satisfaction, I imagine this will have to be tested just as thoroughly. I will do another reddit testing thread once the sparse jit has been merged.

Very strange, I used OBS Studio to record and Handbrake to convert it to h.265 and reduce the file size.

Tested Super Smash Bro's & Echos of Wisdom on M4 Max Macbook Pro. Both seemed to run well

Have you profiled this to check that the JIT is not already performing any relevant optimizations or is this just something that is suggested by IDE? As most of these contain very few potential branches, I'm unsure if the runtime would not simply lower this into identical IL.
