Based on https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/blob/05973d8aeb1a4d12f59aadfb86d20decadba82d1/include/vk_mem_alloc.h#L2842

Is this meant to reduce the size of the lib?

It's something I noticed when I was comparing the upstream code vs the vendored third party. It's mostly for consistency, but it could benefit the lib size.

I think the proper way to address this is actually to update our third_party vendor lib.
