Revert "Reland "[fuchsia] Handle UrlRequestRewriteRulesProvider in CastRunner.""

This reverts commit bb05b31107.

Reason for revert: Still some compatibility issues between the client
and server implementations, so revert until those can be diagnosed.

Original change's description:
> Reland "[fuchsia] Handle UrlRequestRewriteRulesProvider in CastRunner."
>
> This is a reland of bbd8d1507c, now that the
> peer-component's implementation of the UrlRequestRewriteRulesProvider works
> correctly.
>
> Original change's description:
> > [fuchsia] Handle UrlRequestRewriteRulesProvider in CastRunner.
> >
> > * Implement handling of the
> >   chromium.cast.UrlRequestRewriteRulesProvider API in CastRunner.
> > * Remove handling of the fuchsia.web.AdditionalHeadersProvider API in
> >   CastRunner as it is deprecated.
> > * Adapt the integration test to use the new API.
