IVGCVSW-6338 IMemoryOptimizerStrategy Create a wrapper validator strategy

 * Add validator wrapper
 * Add validation logic:
    Condition #1: All Memblocks have been assigned to a MemBin

    Condition #2: No Memblock is assigned to multiple MemBins

    Condition #3: No two Memblocks overlap in both the X and Y axis
                  Memblocks can overlap on the X axis for
                  SingleAxisPacking
                  Memblocks can overlap on the Y axis or
                  the X for MultiAxisPacking but not both

 * Add test strategies and tests for overlap, duplicates
   and unassigned blocks
