c++: Avoid [[nodiscard]] warning in requires-expr [PR98019]

If we aren't really evaluating the expression, it doesn't matter that the
return value is discarded.

gcc/cp/ChangeLog:

PR c++/98019
* cvt.c (maybe_warn_nodiscard): Check c_inhibit_evaluation_warnings.

gcc/testsuite/ChangeLog:

* g++.dg/cpp2a/concepts-nodiscard1.C: Remove xfail.
