x86/idtentry: Provide IDTENTRY_IST
Same as IDTENTRY but for exceptions which run on Interrupt Stacks (IST) on
64bit. For 32bit this maps to IDTENTRY.
There are 3 variants which will be used:
IDTENTRY_MCE
IDTENTRY_DB
IDTENTRY_NMI
These map to IDTENTRY_IST, but only the MCE and DB variants are emitting
ASM code as the NMI entry needs hand crafted ASM still.
The function defines do not contain any idtenter/exit calls as these
exceptions need special treatment.
