  [clang] Add test for CWG170 "Pointer-to-member conversions" (#121667)

This patch adds test for
[CWG170](https://cplusplus.github.io/CWG/issues/170.html). The
resolution adds explicit undefined behavior, so I think the best we can
do is to put the test into constexpr evaluator. Change to
[expr.static.cast] is not tested, because it was a drive-by fix that
removed an impossible case (I confirmed it using minutes). Minutes
mention several times a comprehensive paper in this design space which
no one seem to remember. I believe it's
[P0149R0](https://wg21.link/p0149r0) "Generalised member pointers".
