QQuickControl: update baseline offset automatically

...unless explicitly defined. All buttons repeated the same binding.

[ChangeLog][Controls][Control] Unless explicitly specified, baselineOffset
is now automatically updated based on the top padding of the control and
the baselineOffset of the contentItem. Styles no longer need to specify
the baselineOffset in QML.
