VMA also provides convenience functions that create a buffer or image and bind it to memory
represented by an existing #VmaAllocation:
vmaCreateAliasingBuffer(), vmaCreateAliasingBuffer2(),
vmaCreateAliasingImage(), vmaCreateAliasingImage2().
Versions with "2" offer additional parameter `allocationLocalOffset`.
Remember that using resources that alias in memory requires proper synchronization.
You need to issue a memory barrier to make sure commands that use `img1` and `img2`
don't overlap on GPU timeline.
