Reviewed by Antonio Gomes.

Source/WebCore:

This patch adds the willRespondToMouseClickEvents and willRespondToMouseMoveEvents
functions, named after similar functions in the iOS fork of WebKit.

Touch-adjustment will now use these two functions, which improves accuracy when
targeting shadow-dom elements, and also means touch adjustment will prefer enabled
form-elements over disabled ones.
