Store profile per thread (#31907)

This allows storing the profile per thread, as well as moving the logic
of which tools are enabled or not to the profile itself.

This makes it much easier to switch between profiles, means there is
less global state being changed on every profile change.

Release Notes:

- agent panel: allow saving the profile per thread
