Universal: ensure setting background/foreground works

- Add HasGlobalForeground and HasGlobalBackground. These are set
to true when a foreground/background color is specified via settings
(qtquickcontrols2.conf file or environment variables), and then used
to initialize each attached style object's m_hasForeground and
m_hasBackground property.
- Add tst_qquickuniversalstyleconf auto test to ensure that global
settings are respected.
