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.
This is not a continuation of the Metal backend; this is simply bringing
the branch up to date and merging it as-is behind an experiment.

* GPU: Migrate buffers on GPU project, pre-emptively flush device local mappings
Essentially retreading #4540, but it's on the GPU project now instead of the backend. This allows us to have a lot more control + knowledge of where the buffer backing has been changed and allows us to pre-emptively flush pages to host memory for quicker readback. It will allow us to do other stuff in the future, but we'll get there when we get there.
Performance greatly improved in Hyrule Warriors: Age of Calamity. Performance notably improved in TOTK (average). Performance for BOTW restored to how it was before #4911, perhaps a bit better.
- Rewrites a bunch of buffer migration stuff. Might want to tighten up how dispose stuff works.
- Fixed an issue where the copy for texture pre-flush would happen _after_ the syncpoint.
TODO: remove a page from pre-flush if it isn't flushed after a certain number of copies.
* Add copy deactivation
* Fix dependent virtual buffers
* Remove logging
* Fix format issues (maybe)
* Vulkan: Remove backing swap
* Add explicit memory access types for most buffers
* Fix typo
* Add device local force expiry, change buffer inheritance behaviour
* General cleanup, OGL fix
* BufferPreFlush comments
* BufferBackingState comments
* Add an extra precaution to BufferMigration
This is very unlikely, but it's important to cover loose ends like this.
* Address some feedback
* Docs
* Implement vertex and geometry shader conversion to compute
* Call InitializeReservedCounts for compute too
* PR feedback
* Set clip distance mask for geometry and tessellation shaders too
* Transform feedback emulation only for vertex
