Adds nsISubstitutionObserver so that substitutions set on a
parent nsISubstitutingProtocolHandler which are then propagated
to child processes can be observed in the child.
Updates test_extensionURL.html to set substitutions on the parent
ExtensionProtocolHandler before trying to load moz-extension URI's
using those substitutions.
