Remove libstatsmetadata

Remove kWhitelistedAtoms usage in MetricsManager and remove:
- atoms_info references from statsd
- libstatsmetadata usages from statsd
- libstatsmetadata library
- atoms_info_writer.h/.cpp
- references to atoms_info in rest of stats-log-api-gen
- allow_from_any_uid annotation
