chore: clean up ambient (#136)

* fix: remove unnecessary tx field in ProtocolComponent

* chore: move ambient protobuf files to ambient module

* chore: remove dependency on common message types

This allows us to isolate the ambient specific messages within the ambient module

* feat: update ambient substream with new message structs

* chore: update substream configs

And remove use of deprecated BlockContractChanges.

* feat: implement From for AmbientProtocolComponent to ProtocolComponent
