Add a Vulkan Renderer

[ZironZ]

This would be useful for a few reasons.

1. It should help with some of the performance issues around scaling individual textures/sprites.
2. It would allow Mac users to use all the compute shader GPU scaling options.
3. It will make it easier to add support for DLAA and DLSS.

The simplest way to add a Vulkan renderer is probably to port the one in WatermelonDS. It is a bit buggy, but it could always be marked as "experimental".
