Prepare for compat-framework support

- Create a Context for the system server
- Add the target SDK level to RavenwoodConfig
- Allow PropertyInvalidatedCache sysprops
- Copy StatsD classes, until we get a proper support
- Copy Compatibility and some annotations from libcore
- Keep FrameworkStatsLog
