WIP: Add Critical path configuration menu and critical path view

Note that code is hard-coded. A generic way is needed to configure
the menu and command-handler driven by the server.

Alternatively, this feature could be added in a third-party, trace
compass specific front-end extension(s) (i.e. Theia extension/Vscode
extension).
