chore: Migrate modules to use the Module util (#7964)

**What**
Apply the `Module` util to each module to handle the export and provide the linkable configuration object.

- Most joiner config that does not have any special config are removed/cleaned up in favor of the autogenerated one or simpler one
- linkable are now available in all modules
- cleaned up the dependencies of the modules
