Add attribute to disable QSessionManager
Loading a session manager can be problemtatic for system services that
are always auto-activated or small DBus activated helpers which
shouldn't really be restored nor gain anything from a session.
The current solutions is to connect to commitDataRequest and
saveStateRequest and then reset a restart hint.
It's very unintuitive and somewhat wasteful given the X session manager
is full of slow blocking calls.
Rather than changing the behavior of QGuiApplication and handling null
pointers, this patch loads the base QPlatformSessionManager that is used
by QPAs that don't have a session manager.
