pw_web_ui: Improve error handling of WebSerialTransport

Don't throw an error if a user tries to reconnect to a port. Pass errors
in an 'errors' observable that consumers can subscribe to. Don't put the
'chunks' observable into an errored state, since that prevents it from
ever sending anything else again, and we often want to continue reading
despite an error.
