Sven van Haastregt 8e74722a0a cmake: Fix -Wno- handling in add_cxx_flag_if_supported (#1656) ...

The `-Wno-...` compiler flags only result in a diagnostic if another
diagnostic is emitted.  When passing such flags to
`add_cxx_flag_if_supported` (and `check_cxx_compiler_flag`), the test
would always succeed.  For such cases, test the `-W...` flag instead
of the `-Wno-...` flag.
