\brief Given an allocation, returns Win32 Handle, that may be imported by other processes or APIs.
`hTargetProcess` must be a valid handle to target process or NULL. If it's `NULL`, the function returns
handle for the current process.
If the allocation was created with `VMA_ALLOCATION_CREATE_EXPORT_WIN32_HANDLE_BIT` flag,
the function fills `pHandle` with handle that can be used in target process.
