Move signals_slots to ScriptMutationObservers (#39275)

Browse source 
Both places where we access signals_slots already have a reference to
ScriptMutationObserver. This saves us another access to
with_script_thread.


Testing: This does not change functionality.
Fixes: Part of addressing: https://github.com/servo/servo/issues/37969
