Add a run menu (#32505)

As part of this I refactored the logic that enabled/disabled actions in
the debugger to happen at action registration time instead of using
command palette filters. This allows the menu to grey out actions correctly.

Release Notes:

- Add a "Run" menu to contain tasks and debugger
