[iframe] Reset the size when navigating cross-origin
This patch resets the intrinsic size info from `<iframe>`
content when the content navigates cross-origin, to prevent
leaking the size information.
To do this, when `DocumentLoader` for an `<iframe>` child
content checks if it's a cross-origin navigation in
`CommitNavigation()`, and clears the natural dimension if so.
`FrameLoader` is changed to keep the old document origin.
`RenderWidgetHostViewChildFrame` needs a new queue for the
intrinsic size events, as its `frame_connector_` isn't set yet
at the `CommitNavigation()` timing.
`content_switch_dependent_feature_overrides.cc` is needed to
change to enable the flag in the browser when testing. In the
non-testing environments, the flag in Blink and Browser are
automatically synchronized.
The existing test `responsive-iframe-navigation.html` is
extended to test cross-origin as a new variant. In addition,
it tests the initial viewport size of the child frame.
All changes are under a runtime flag.
