[NTOS:EX] Implement NtSetSystemInformation().SystemLoadGdiDriverInSystemSpaceInformation (#8180)

Browse Source 
Implement SystemLoadGdiDriverInSystemSpaceInformation case of NtSetSystemInformation() function.
According to https://www.geoffchappell.com/studies/windows/km/ntoskrnl/api/ex/sysinfo/gdi_driver.htm, it does the similar thing to SystemLoadGdiDriverInformation (these two cases even have the same shared SYSTEM_GDI_DRIVER_INFORMATION structure).
The only difference is, SystemLoadGdiDriverInSystemSpaceInformation uses the global system space (without passing an additional flag to MmLoadSystemImage()), while SystemLoadGdiDriverInformation uses the session space instead.
Since the session space is not supported yet, for now simply redirect SystemLoadGdiDriverInSystemSpaceInformation to SystemLoadGdiDriverInformation case, which we have already implemented. However, this code needs to be updated appropriately (an additional flag should be passed to MmLoadSystemImage() call for SystemGdiDriverInformation as well) once a support for session space is implemented.
This fixes VM starting failure for VirtualBox 3.1.0 - 4.0.24 and 4.3.0 - 4.3.12 versions. Newer versions of VirtualBox still don't work because of another blocking bugs.
