Add the option to match a whitelist of strings in FieldValueMatcher.

+ This is useful when we want to build Anomaly detection on wakelocks, but want to whitelist
wakelocks held by some apps that are whitelisted. It reduces the number of matchers needed
in such a config.

+ Also added the ability to match an AID by string name.
