AMD: Vulkan Memory Allocator 2.2

Vulkan Memory Allocator (VMA) is AMDs single-header STB-like library for easily and efficiently managing memory allocation for your Vulkan games and applications. The last three months of VMA development since the release of v2.1 have mostly focused on significantly improving and fleshing out the memory defragmentation support, adding support for sparse binding, and making sure the library had a rich and robust set of allocation strategies for games and other Vulkan applications to use.
