cmake: standardize USE_THREADS and USE_NSEC Threading can now be disabled with `USE_THREADS=OFF` instead of `THREADSAFE=OFF` to better support the other cmake semantics. Nanosecond support is the default _if_ we can detect it. This should be our default always - like threads - and people can opt out explicitly.
