libservo: Combine LoadStart, HeadParsed, and LoadComplete` messages (#35260)

Browse source 
These will be a single method in the upcoming `WebView` delegate, so it
makes sense to also combine the internal message to match this. In
addition, since `LoadStatus` is now exposed to the API if there is ever
the need to add more statuses or to move to an event-based version, the
API is already set up for this.
