Migrate protobuf definitions to pull from hedera-services repo

[agadzhalov]

Problem

We need to migrate the protobuf definitions from the hedera-protobufs repository to pull from the hedera-services repository. This change is aimed at simplifying the development process and centralizing all Protobuf-related files directly within the hedera-services repo, ensuring they stay in sync with service code.

Solution

Use git submodules to point to a specific commit from which we want to pull the hedera-services repo. Implement/update a command in the Taskfile.yaml to leave only the protobuf files and get rid of all the others.
