sdm660-common: Silence some spammy logging

HWC and cit sensor logspam is so intense it bumps up logd's idle CPU
usage up to over 3%. With this change, logs are much cleaner and logd
idle CPU usage is reduced to under 1%, while still allowing error logs
to pass through.
- Do this only in user/debug builds (except eng).
- Add wifi and cnss too while we're at it, they can get noisy at times.
