QGuiPlatformPlugin: QFileIconProvider and QIcon backend.

Add a backend for QFileIconProvider in the platform plugin

Also change the QIcon::fromTheme backend in the platform plugin:
On KDE, we unfortunately can't use KIcon as backend, as the current
API doesn't let us know easily (and quickly) wether we should use
the fallback or not (KDE always fallback to the question mark
"unknown" icon)
So we will use the QIconLoader even on KDE.
But we need to make sure that the theme name and the icon search paths
are correct. Ask that to the platform plugin
