Bug: 192588767 This change corrects a latent defect related by the new bypass() method in PropertyInvalidatedCache. The defect is not current issue because there are no clients using the bypass() method yet. PropertyInvalidatedCache is modified to work without sytsem properties, because test code generaly does not have permission to read or write properties. The modification has minimal impact when there is not testing in progress. New tests for basic cache functionality are added. Bypass statistics are included in 'dumpsys cacheinfo'. We can identify caches with a low hit ratio due to wildcard users, and revisit the logic for those particular caches. Lint warnings were corrected in the class javadoc comment and by changing all occurrences of String.format() to TextUtils.formatSimple().
