Store TextIndicator rects in screen coordinates, since that's what we
want anyway, and this makes it easier to share this code between the WebKits.

* page/mac/TextIndicatorWindow.mm:
(-[WebTextIndicatorView initWithFrame:textIndicator:margin:]):
(WebCore::TextIndicatorWindow::setTextIndicator):
Avoid some rect conversion because the TextIndicator rects are already in screen coordinates.

Copy the WebKit2 WKActionMenuController TextIndicator implementation
into WebActionMenuController. The only significant difference is
that we build the TextIndicator right at menu construction time
instead of in the Web process.

* WebView/WebHTMLView.mm:
(-[WebHTMLView scrollWheel:]):
Let the WebActionMenuController know that we're handling a scroll.

(-[WebHTMLView mouseDown:]):
Let the WebActionMenuController know that we're handling a mouseDown.

Keep a TextIndicatorWindow on WebView, just like WKView does.
Expose the WebActionMenuController on WebView (internally).

Adjust to the fact that TextIndicator keeps screen-relative rects.
