This is a followup to a previous change switching std::u8string,
std::u16string, and std::u32string to print as string literals instead
of an array of characters. Also update the PrintCharsAsStringTo<Char>()
helper to handle cases where the pointer to the string data is null;
unlike std::basic_string<Char>, std::basic_string_view<Char>'s data()
is allowed to return nullptr.
The new PrintTo overloads complicate the PrintTo(internal::StringView)
overload, which needs to be disabled if internal::StringView is an alias
for std::string_view to avoid multiple definitions with the same
overload. Simply omitting the unconditional PrintTo(std::string_view)
overload is a worse option though, as this results in std::string_view
not printing nicely if internal::StringView is not an alias for
std::string_view.

googletest avoids using the Abseil flag library, so googlemock should
do the same for consistency.
