script: Upgrade node_ids to pipeline_to_node_ids to track the owner pipeline of the node (#37213)

Browse source 
Upgrade `ScriptThread::node_ids` to `pipeline_to_node_ids` to track the
owner pipeline of the node
This will enable webdriver to know if it is requesting element from
other origins and properly distinguish "stale element reference" from
"no such element".

Testing: [Action
run](1538599490), no
regression. We can now pass WebDriver "cross origin" tests.

Fixes: #35749
