QMacStyle: CC_SpinBox is now HITheme-free

Bonus changes in this edition:

    * The focus frame shows only around the spin-box's
      line-edit, as it should. This requires getting
      access to the spin-box's line-edit, which we do
      by setting a property on the former. Notice that
      the stepper doesn't get focus. On this point,
      macOS is inconsistent (partly because there's no
      such thing as an NSSpinBox, and partly because
      spin-box buttons are a separate control), so we
      copy the same focus behavior as NSDatePicker.

    * We clean some QFocusFrame related dead code in
      QMacStyle::event().
