[AppKit Gestures] Cannot mouse drag to resize <textarea>
https://bugs.webkit.org/show_bug.cgi?id=324275
rdar://187497511
Reviewed by Richard Robinson.
<textarea> can be (and on many platforms, by default, is) resizable by
configuring the `resize` CSS property. The resize control interaction
is driven by EventHandler setting `RenderLayer::inResizeMode` and
dispatching mouse events to said control.
Currently, for gesture-driven interactions, we don't let mouse tracking
win on mouse drags over the resize control, so in this patch we teach
InteractionInformationAtPosition to carry an extra bit about whether the
hit point is on such a control, and we teach WKAppKitGestureController
how to prioritize mouse tracking if that position information bit is set.
