Fix text autoscrolling when typing in modern webkit

We have been relying on UIKit to scroll editable text, but
since we cannot give them enough information for them to always
do the right thing, we should just do all the work in WebKit.
This has the added benifit of fixing some tricky autoscrolling
bugs that have cropped up recently.

  • editing/Editor.cpp:

(WebCore::Editor::insertTextWithoutSendingTextEvent):
(WebCore::Editor::revealSelectionAfterEditingOperation):
We should be scrolling the main frame in WebKit. We have been relying on UIKit,
but we cannot give them enough information to guarantee a correct scroll, so just
do all the work in WebKit.

  • page/FrameView.cpp:

(WebCore::FrameView::unobscuredContentRectExpandedByContentInsets const):
Update to use the rect that is actually visible, accounting for the software keyboard.

Source/WebKit:

For staging only. We need to turn off UIKit's scrolling behavior to land
the changes we are making. To keep from the build ever breaking,
I am temporarily circumventing the changes in UIKit. This will be removed
once the next UIKit submission happens.

  • UIProcess/ios/WKContentViewInteraction.mm:

(-[WKUIWKTextInteractionAssistant scrollSelectionToVisible]):
(-[WKContentView setUpTextSelectionAssistant]):
