[Side Search] Leverage protobuff data types for state restore.

Replaces usage of the base::Value data type in favor of custom side
search specific protobuff data types that are serialized/deserialized as
strings. By leveraging protobuff, we can leverage its capabilities when
it comes to data versioning and reduce developer complexity that may
arise when needing to support changing data types.

This was proposed while discussing the related CL (see below). The
protobuff types will be leveraged too for serializing and deserialing
extra_data in pickle data.
