    libstdc++: Use char for _Utf8_view if char8_t isn't available [PR114519]

    Instead of just omitting the definition of __unicode::_Utf8_view when
    char8_t is disabled, we can make it use char instead.

    libstdc++-v3/ChangeLog:

            PR libstdc++/114519
            * include/bits/unicode.h (_Utf8_view) [!__cpp_char8_t]: Define
            using char instead of char8_t.
            * testsuite/ext/unicode/view.cc: Use u8""sv literals to create
            string views, instead of std::u8string_view.
