Moved AppLibrary, Configuration, and PlayReport namespaces to Ryujinx.Systems, add the compat list stuff in the base Ryujinx.Systems namespace.
Moved the compatibility UI stuff to the proper UI view/viewmodel folders.
Metal sounded like a good idea to get in the emulator but frankly I
underestimated just how experimental and not ready it was.
From my write up in the Discord:
```
As is, Metal supports only a few games.
The games it does support freeze on first use of not playing them via Vulkan, because shader translation is broken.
So you need to use a dirty hack to not delete all your shaders.
Not to mention it breaks many games via MoltenVK because of changes to the shared GPU code.
Merging Metal seemed like a great idea, because of the few games it does support.
But I don't think it's worth it. Many of the games it breaks via MoltenVK *don't work via Metal*.
Which effectively makes current Ryubing worse for Mac users than Ryujinx 1.1.1403.
I think what I'm gonna do is revert Metal, and reopen it as a PR. That way, you can still take advantage of the Metal backend as is, but without making other games worse with no solution.
```
For what it's worth, the shader translation part could at least be
"fixed" by always applying a 30ms delay for shader translation to Metal.
That being said, that solution sucks ass.
The MoltenVK regressions are even worse.
I hope this is not a let down to the Mac users. I hope you realize I'm
reverting this because you're actively getting a worse experience with
it in the emulator.
Note: this setting is global, even though it appears in the settings for the individual gamepad. This is simply for consistency; you access all the rainbow stuff in one place.
Quality of life feature
Similar in function to the "Start Games in Fullscreen" toggle
For users who want to run games in windowed/non-fullscreen mode with
menu UI hidden, this eliminates the need to always click "Hide UI"
