Update QIconLoader system theme names on QWSI ThemeChange

Browse Source 
The GTK platform theme (and possibly others) emit theme change
when the named icon theme changes, but that was not propagated
to QIconLoader.

We now call QIconLoader::updateSystemTheme(), but note that
if a user theme has been set we ignore the system theme update
and will end up with a stale value, even if the user theme is
later cleared. This will be fixed in a follow up commit.

Pick-to: 6.6 6.5
