Fix wide char related tests on Cygwin

This makes the wide char tests run by `./fish_tests` pass on systems where
sizeof wchar_t is two (e.g., Cygwin). In doing so it corrects several
problems with the underlying code in module *utf8.cpp* such as allowing
five and six byte UTF-8 sequences. They were allowed by the original
Unicode proposal but are not allowed by the adopted standard.
