VS2017 reports 'warning C4028: formal parameter 2 different from declaration' for the library constructor and destructor interfaces for the Generator modules. VS2017 compiler also reports similar warnings for the DXE entry points. Remove the CONST qualifier for the SystemTable pointer (the second parameter to the constructor/destructor/DXE Entry point) to make it compatible with the formal declaration.
