debugger: Debug sessions rerun build tasks by default when restarting (#33724)

We reworked the debug modal spawning to use the task context from past
debug sessions when spawning a debug scenario based on task inventory
history.

We changed restart session keybinding to rerun session too.

Closes #31369

Release Notes:

- Restarting a debug session now reruns build tasks that are associated
with the session
