Vulkan doesn't have a memory allocator builtin. The application should provide the memory allocator at runtime. Vulkan Memory Allocator is a widely used implementation. Vulkan Memory Allocator is a header only implementation, but the using application should compile a part in a CPP compile unit. The file `vk_mem_alloc_impl.cc` and `extern_vulkan_memory_allocator` library is therefore introduced. Reviewed By: fclem Differential Revision: https://developer.blender.org/D16572
