[KE]
Misc trap/interrupt fixes:
- Stub legacy KiGetTickCountHandler (INT 2A) to fail instead of breakpointing. We have
made it so far without it, and if someone finds something that actually uses this instead
of Win32's GetTickCount we can add it then. Raises the bar of making ReactOS
breakpoint from 2 bytes to 4.
- Bugcheck with the right status code in case Kei386EoiHelper is called (which means you
are trying to load a Windows HAL which we totally do not support right now).
- Use Ke* instead of Kf* in C code for IRQL routines.
