Fix clang -Wdeprecated-copy.

The copy constructor must be explicitly defined (here, defaulted) to be
available when the assignment operator is deleted.  While there is a
templated constructor from VmaStlAlloc<U>, the compiler doesn't consider
this to be a "copy" constructor for purposes of the warning.
