Add attribute to indicate a widget was the target of a style sheet

Qt already has the widget attribute WA_StyleSheet to which indicates that
a widget was subject to a style sheet, but it doesn't indicate that the
widget was actually affected by the style sheet. For example, an application
style sheet will set the WA_StyleSheet attribute on all widgets, even if it
only targets QPushButtons. The WA_StyleSheetTarget new attribute pairs with
WA_StyleSheet to give this extra information.

[ChangeLog][QtWidgets] Added the Qt::WA_StyleSheetTarget attribute to
indicate that a widget was affected by a style sheet.
