Support ConstCharArrayDetector also for UTF-16 arrays

The long-term benefit will be support of C++11 char16_t string literals (for
cases of string literals with non-ASCII content) once we drop any compilers that
don't support those yet.  The short-term benefit is support for an improved
OUStringLiteral1 that accepts any sal_Unicode value, not just ASCII ones (see
next commit).
