CynthiaOketch 9af19158f3 devtools: Show service workers in Firefox DevTools about:debugging (#43659) ...

This update makes service workers properly show up in DevTools and
behave more like dedicated workers.

- Added an is_service_worker field to DevtoolsPageInfo so the devtools
server can tell service workers apart from dedicated workers
- Triggered a NewGlobal message when a service worker is created in
serviceworker_manager.rs, similar to what already happens for dedicated
workers
- Routed service workers to root.service_workers so they appear under
"Service Workers" in about:debugging instead of "Other Workers"
- Implemented listServiceWorkerRegistrations with the expected response
format (activeWorker, installingWorker, waitingWorker, evaluatingWorker)
to match Firefox’s LegacyServiceWorkersWatcher
- Added support for getPushSubscription in WorkerActor, currently
returning subscription: null
Enabled the service_worker target type in the watcher’s SessionContext
and handled watchTargets("service_worker")

Testing

Start Servo with:

`RUST_LOG="error,devtools=debug" ./mach run --
--pref=dom_serviceworker_enabled --devtools=6080
"https://mdn.github.io/dom-examples/service-worker/simple-service-worker/"
`

In Firefox, go to about:debugging and connect to localhost:6080
Confirm the service worker shows up under "Service Workers"



Fixes #43574
