Martin Robinson 6842da5f5b script: Use the Weak<ScriptThread> reference for tracing instead of thread-local storage (#42657) ...

This changes makes it so that tracing accesses the `ScriptThread` via a
weak reference set on the `Runtime` rather than thread local storage.
The idea is to use TLS less and less as time goes on. This is done by
creating a new data structure that holds all the data that is necessary
for SpiderMonkey callbacks in the `ScriptThread`.

Testing: This should not change behavior in a way that is observable
via testing.
