[auto-iso] Set remote frame tokens

This patch adds a JS script to FormHandlersJavaScriptFeature
that makes each frame register a remote frame token associated
to its frame id. The remote frame token is stored in the DOM
so it can be accessed from the page content world as well.

Once Autofill is moved to the isolated world, this will serve
to match the WebFrame corresponding to a page in the page
content world to its equivalent in the isolated content world.

Matching WebFrames for the same page is necessary for moving
Autofill to the isolated content world while keeping some
scripts in the page content world. This way the browser layer
can route events originating in the page content world to
the correct Autofill components, which all bound to the
isolated world space.

A subsequent CL will use the remote frame token in the DOM
in the payload of Autofill page content world scripts.
