This adds a vulkan backend to GHOST. The code was extracted from the tmp-vulkan branch. The main difference with the original code is that GHOST isn't responsible for fallback. For Metal backend there is already an idea that the GPU module is responsible for the fallback, not the system. For Blender we target Vulkan 1.2 at the time of this patch. MoltenVK (needed to convert Vulkan calls to Metal) has been added as a separate package. This patch isn't useful for end-users, currently when starting blender with `--gpu-backend vulkan` it would crash as the `VBBackend` doesn't initialize the expected global structs in the GPU module. Validated to be working on Windows and Apple. Linux still needs to be tested. Reviewed By: fclem Differential Revision: https://developer.blender.org/D13155
