script: Make timers per-process (#34581)
Before all timers were managed by the Constellation process, meaning that they had to trigger IPC calls to be scheduled and fired. Currently, timers are only used in the `ScriptThread`, so it makes sense that they are per-process. This change restores the timer thread functionality that existed before avoided entirely. Completion is done using a callback that is sent to the timer thread similarly to how fetch is done. This allows reusing the existing task queue without making any new channels. Fixes #15219.
