Log:
- Combine SeInit1 and SeInit2 into SeInit since both can be done together now.
- Call PsInitSystem instead of PspInitPhase0, since PsInitsystem is the
"external" phase-choosing routine.
- Implement ExComputeTickCountMultiplier to create a 24-bit precision remainder + whole
integer of the ms/clock tick used in SharedUserData.
- Set the OS version and Machine Type (i386/PPC (<3 Arty) in SharedUserData.
- Move some HAL calls in Phase 2 (actually Phase 1...), same for KeInit2.
- Break into KDBG a bit earlier.
