Pluginize the platform styles

This enforces decoupling and in the case of QMacStyle, isolates
QtWidgets and therefore end user applications, from Carbon/HITheme.

Windows and Fusion are platform independent, so they remain built-in
(but mostly because the Windows style is tightly coupled to other styles
like QStylesheetStyle).
