c++: disable -Wnonnull in unevaluated context [PR115580]

This PR complains that we issue a -Wnonnull even in a decltype.
This fix disables even -Wformat and -Wrestrict.  I think that's fine.

PR c++/115580

gcc/c-family/ChangeLog:

* c-common.cc (check_function_arguments): Return early if
c_inhibit_evaluation_warnings.

gcc/testsuite/ChangeLog:

* g++.dg/warn/Wnonnull16.C: New test.
