* vk: Add `VK_EXT_provoking_vertex` optimization
The dreamcast uses the last vertex as the provoking vertex, while vulkan uses the first vertex.
This requires an additional call to `setFirstProvokingVertex` to reorder the vertices for all incoming geometry.
With `VK_EXT_provoking_vertex`, the pipeline can designate that the provoking vertex is to be the last vertex, which removes the need to re-order incoming geometry on the CPU.
* vk: Propagate physical device API version to VMA
Allows VMA to make assumptions such as using the `*KHR` or non-`KHR` versions of certain function names.
* vk: Refactor libretro device initialization for `VK_EXT_provoking_vertex`
* vk: Top out at vulkan API version to VMA to 1.1
Despite the physical device possibly being 1.2 or 1.3, we only want up to 1.1. Otherwise we will be responsible for other API functions being resolved and loaded when passing to VMA.
* vk: Enable `VK_EXT_provoking_vertex` usage for ModVol and Final(OIT) pipeline
* vk: Enable `VK_EXT_provoking_vertex` for ModVol(OIT) pipeline
Pretty much anything handling dreamcast-geometry should use this extension when available
* vk: Additional `VK_EXT_provoking_vertex` pipeline fixes
