Jit cache now fully resets when booting a game multiple times.
This should fix random jit cache crashes.
Also removed some redundant code related to region allocation and fixed
PPTC Purge not fully purging all PPTC files in the backup folder.
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.
- paired devices have notifications that they are configured and require connection
- paired devices load the configuration when connected
- A notification appears when changing control configuration settings.
- Now control settings will be saved only when they are changed
- Added a button to roll back changes to the previously saved state
- Fixed a bug: when switching the "player", if the "input device" and "controller type" settings were changed, the save dialog box did not appear.
- "Motion", "Rumble" and "Led" also have events notifying about changes
