Added transparency-metadata display.

This feature enables 'App Details' to support MBAs with metadata file and display in an offline UI. This change includes a new fragment and user view that sources data from within any MBAs apk file that contains application-metadata.xml.

Test: make -j64 RunSettingsRoboTests , AVD manual test
