[482528] Fix inconsistencies in FontFormat property sections

Use custom property sections (with checkboxes) for:

- WidgetStyle.labelFontFormat, which is common to all widgets and
  corresponds to the format of the widget's "header" label;

- LabelWidgetStyle.fontFormat, HyperlinkWidgetStyle.fontFormat and
  TextWidgetStyle.fontFormat, which correspond to the format of the
  actual text for the corresponding widgets, TextWidgetStyle being
  shared by both Text and TextArea widgets (TextArea inherits from
  Text).
