refactor: extract trin-execution/e2store + clean dependencies

[KolbyML]

What was wrong?

• Trin Execution started in portal-bridge types, but was rapidly outgrowing its position here.
• E2store (era/era1 support) is useful for more then just the bridge
• we had a lot of unused dependencies in our Cargo.toml files

  How was it fixed?

  1. I moved Trin Execution into its own crate, which will allow development of it to expand. It will also allow 3rd party contributors from the EPF to more easily find it to contribute to it. I have already had a person who thought it was a cool project.
  2. I moved e2store/era/era1 to it's own crate
  3. I cleaned up our dependencies
