Consider using rvalue friend function in FileMappedResizableDirectMemory::Close()

[konard]

Location: cpp/Platform.Memory/FileMappedResizableDirectMemory.h:66

Current code:

// TODO: maybe use rvalue friend function
public: void Close()
{

}

Issue:
The Close() method is currently empty and there's a suggestion to consider using an rvalue friend function instead of the current approach.

Suggestion:
Evaluate whether using an rvalue friend function would be more appropriate for this use case and implement if beneficial.
