Regression introduced into LIBO_INTERNAL_ONLY code with
1da6908173 "add string_view variants of methods to
O[U]StringBuffer".
And add some tests. Assigning an OStringChar to an OStringBuffer also uses the
std::string_view assignment operator, so also test that with testOStringChar,
even though there it is relatively likely that the OStringChar temporary is
followed by null bytes, which could make the test happen to erroneously succeed.
But at least tools like ASan or Valgrind could catch that. On the other hand,
assigning an OUStringChar to an OUStringBuffer does not use the
std::u16string_view assignment operator (and rather uses a
ConstCharArrayDetector-based one, which was similarly broken and has been fixed
in b66387574e "Fix -Werror=array-bounds"), so
there's no test for that here.
