- By default, all calls to functions that take `VmaAllocator` as first parameter
are safe to call from multiple threads simultaneously because they are
synchronized internally when needed.
- When the allocator is created with `VMA_ALLOCATOR_EXTERNALLY_SYNCHRONIZED_BIT`
- When the allocator is created with `VMA_ALLOCATOR_CREATE_EXTERNALLY_SYNCHRONIZED_BIT`
flag, calls to functions that take such `VmaAllocator` object must be
synchronized externally.
