libpayload/x86/exception: Add ability to ignore unknown interrupts
This will make enabling the APIC safer by ignoring unknown interrupts
and not halting the system. Once all interrupt sources have been found
and handled DIE_ON_UNKNOWN_INTERRUPT can be set if desired.
BUG=b:116777191
TEST=Booted grunt, halted the kernel, and pushed the power button while
in S5. Verified that depthcharge logged the unknown exception.
APIC Init Started
APIC Configured
Ignoring interrupt vector 39
