Third party Windows interrupt controller support if you are brave enough

HalInterrupt.md

Extracted from Windows public symbol, with a bit guessing. Function prototypes are not fully understood yet.

You still need your own way to hook your things into HAL.dll, as interrupt controller extension is never exposed.
