INPUT_MULTIPLE_FIELDS_UI: Mouse click not on sub-fields in multiple fields input  should not move focus
https://bugs.webkit.org/show_bug.cgi?id=109544

Reviewed by Kentaro Hara.

Source/WebCore:

This is similar to Bug 108914, "Should not move focus if the element
already has focus." We fixed a focus() case in Bug 108914. However we
still have the problem in a case of focusing by mouse click.

The fix for Bug 108914 intercepted focus() function to change the
behavior. However focus-by-click doesn't call focus(), but calls
FocusController::setFocusedNode. To fix this problem, we introduce
oldFocusedNode argument to handleFocusEvent, and
BaseMultipleFieldsDateAndTimeInputType::handleFocusEvent restores the
focus to oldFocusedNode if oldFocusedNode is one of sub-fields.
handleFocusEvent is called whenever the focused node is changed.

We don't need InputType::willCancelFocus any more because the new code
in handleFocusEvent covers it.
