cppcheck: Suppress constParameterCallback errors
We have several functions which are used as callbacks for NS_CALL() which only read their void * parameter, they don't write it. The constParameterCallback warning in cppcheck 2.14.1 complains that this parameter could be const void *, also pointing out that that would require casting the function pointer when used as a callback. Casting the function pointers seems substantially uglier than using a non-const void * as the parameter, especially since in each case we cast the void * to a const pointer of specific type immediately. So, suppress these errors. I think it would make logical sense to suppress this globally, but that would cause unmatchedSuppression errors on earlier cppcheck versions. So, instead individually suppress it, along with unmatchedSuppression in the relevant places.
