fix[devtools]: allow element updates polling only if bridge is alive (#27067)

When some element is inspected in DevTools, we have a polling which
updates the data for this element.
Sometimes when service worker dies or bridge is getting shutdown, we
continue to poll this data and will spam with the same "timed out
error".

These changes add an explicit check that polling is allowed only while
bridge is alive.
