UefiCpuPkg CpuDxe: Fix bug with CPU Arch RegisterInterruptHandler
...
The change in r10765 introduced an issue where inherited interrupt
handlers would override the driver's RegisterInterruptHandler
functionality.
DUET installs a IDT with 256 entries early in it's boot. Therefore,
no interrupt handlers could be installed with DUET while using
UefiCpuPkg/CpuDxe (instead of DuetPkg/CpuDxe).
This change forces the IDT to be modified when RegisterInterruptHandler
is called to ensure the UEFI handler will be installed properly.
