📄 Description

Adds MoltenVK as an external built from source. This adds very little to the macOS build time, and provides a few key benefits:

Allows us to easily update to any MoltenVK revision we want for fixes and improvements, rather than working on their quarterly release cycle.
Allows us to create MoltenVK builds with MVK_USE_METAL_PRIVATE_API=1. This gives access to a few extra features that use private Metal APIs, such as sampler mip LOD bias.
Simplifies the build process with one less external pre-built dependency.

MoltenVK recently removed the old VK_NV_glsl_shader extension and some associated dependencies, which cut down the build complexity and made this more viable.

There's already a few nice to haves we get from this ahead of the next release as well:

Support for some more pixel formats like B5G6R5UnormPack16.
Fixes for compute shader internal compiler errors.
