VMM,SUPLib: Adjustments for running tstPDMQueue in driverless mode on hardened windows builds. This adds a fFlags parameter to VMR3Create and defines VMCREATE_F_DRIVERLESS, allowing it to switch between default and driverless suplib initialization. The default CFGM config constructor was amended to enable the IEM fallback option by default (only relevant to amd64/x86).
