[DevTools] Buffer Bridge messages during extension reconnects (#37075)

Buffers Bridge messages during extension port reconnects and adds a
readiness handshake for ordered queue flushing. Includes regression
coverage for reconnect delivery and listener cleanup.

Potential scenario could be a long user session, where Chrome kills one
of the extension ports to save resources and then user re-connects by
navigating back to the DevTools UI.
