[ios] Stop saving/restoring PageDisplayState

This was used to serialize the zoom level and scroll position of a
page when saving the session, however, this is only used when the
feature kRestoreSessionFromCache is disabled or when running on a
version of iOS older than 15.0.

kRestoreSessionFromCache is launched at 100% since M-100 and the
deployment target has been bumped in https://crrev.com/c/4381944
to iOS 15.0+, this means that this is only used when the WebKit
sessionState cannot be saved or is too large to be saved. It is
not deemed worth keeping the code for those unlikely scenarios.

This is part of a multi-CL change:
