Add common resourceId to network events (#37707)

- Add a `resource_id` field to `EventActor` and `NetworkEventActor`
- Store a `next_resource_id` field in DevtoolsInstance
- Add `resource_id` parameter to `NetworkEventActor::new`
- Increment `next_resource_id` when
`DevtoolsInstance::find_network_event_actor` is called so each network
event has a unique id

Testing: Ran servo in devtools mode and can see the data showing in
`status`,`type`, `transferred` ,`size` and `timeline` columns of each
request, also logged the devtools instance and can see unique
`resourceId` for each request.
Fixes: https://github.com/servo/servo/issues/37661
