viewStateDidChange should always fully update ViewState
https://bugs.webkit.org/show_bug.cgi?id=133159

Reviewed by Anders Carlson.

Currently WebPageProxy::viewStateDidChange is passed a mask of bits to update.

This has the following negative consequences:
 – WKWebView implicitly requires more detailed knowledge of the internal implementation of the PageClient.
 – Updates may unnecessarily be split over multiple IPC messages.
 – In order to support partial updates we make multiple virtual function calls to PageClient, which then makes duplicate objc calls.

Better to just always update the entire ViewState.
