Extract protobuf database into a new 'leveldb_proto' component

Code extracted from components/dom_distiller/core/dom_distiller_database.*

Slight API change: callers to UpdateEntries now have to pass a vector of (string, proto) as key and value, instead of just a vector of protos where key is derived.

Ran clang-format on the files I touched so you may see some diffs.

Note: Implementations are in proto_database_impl.h and fake_db.h for proper linking.
