Write a new test which covers readback using vmaCopyAllocationToMemory?

[IAmNotHanni]

Since there is now a test which explains vmaCopyMemoryToAllocation in detail (see pr https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator/pull/474), it might be worth to write one more tests which deals with vmaCopyAllocationToMemory. We could also embedd the actual code from that test in the docs then, instead of displaying uncompiled and untested code in the section "Recommended usage patterns".

Agreed, this may be a good idea. However, I am not sure if a code taken from a test would look good in the documentation. Copy-paste with some modifications to improve the readability as a standalone code sample could work better.
