IVGCVSW-7168 Add Conv2d and Constant support to TOSA Reference Backend

 * Added TOSA Conv2d and Constant mappings.
 * Added unique naming to mappings based on previous and following
   layers, so they are connected correctly.
 * Updated existing mappings with new naming convention.
 * Added all mappings to one main block in OptimizeSubgraphView.
 * Removed isMain from mapping functions.
 * Added Conv2d EndToEnd test.
