Vulkan: Add workarounds for MoltenVK (#4202)

* Add MVK basics.

* Use appropriate output attribute types

* 4kb vertex alignment, bunch of fixes

* Add reduced shader precision mode for mvk.

* Disable ASTC on MVK for now

* Only request robustnes2 when it is available.

* It's just the one feature actually

* Add triangle fan conversion

* Allow NullDescriptor on MVK for some reason.

* Force safe blit on MoltenVK

* Use ASTC only when formats are all available.

* Disable multilevel 3d texture views

* Filter duplicate render targets (on backend)

* Add Automatic MoltenVK Configuration

* Do not create color attachment views with formats that are not RT compatible

* Make sure that the host format matches the vertex shader input types for invalid/unknown guest formats

* FIx rebase for Vertex Attrib State

* Fix 4b alignment for vertex

* Use asynchronous queue submits for MVK

* Ensure color clear shader has correct output type

* Update MoltenVK config

* Always use MoltenVK workarounds on MacOS

* Make MVK supersede all vendors

* Fix rebase

* Various fixes on rebase

* Get portability flags from extension

* Fix some minor rebasing issues

* Style change

* Use LibraryImport for MVKConfiguration

* Rename MoltenVK vendor to Apple

Intel and AMD GPUs on moltenvk report with the those vendors - only apple silicon reports with vendor 0x106B.

* Fix features2 rebase conflict

* Rename fragment output type

* Add missing check for fragment output types

Might have caused the crash in MK8

* Only do fragment output specialization on MoltenVK

* Avoid copy when passing capabilities

* Self feedback

* Address feedback
