qt5.qtwebengine: drop overrideSDK

        #   starting with clang 16. Patches are available upstream that can be backported.

        # Because the first error is non-trivial to fix and suppressing it risks future breakage,

        # clang is pinned to clang 15. That also makes fixing the second set of errors unnecessary.
