debugger: Add run to cursor and evaluate selected text actions (#28405)

## Summary

### Actions

This PR implements actions that allow a user to "run to cursor" and
"evaluate selected text" while there's an active debug session and
exposes the functionality to the UI as well.

- Run to cursor: Can be accessed by right clicking on the gutter
- Evaluate selected text: Can be accessed by selecting text then right
clicking in the editor

### Bug fixes

I also fixed these bugs as well

- Panic when using debugger: Stop action
- Debugger actions command palette filter not working properly in all
cases
- We stopped displaying the correct label in the session's context menu
when a session was terminated

Release Notes:

- N/A
