ArmPkg: Make variables used for GicInterrupt UINTN

Although the maximum interrupt ID on GicV2 is 10bit and for GicV3/4 is
24bit, and that the IAR and EOIR registers of the Gic CPU interface are
32 bit; the typedef HARDWARE_INTERRUPT_SOURCE is defined as UINTN in
EmbeddedPkg\Include\Protocol\HardwareInterrupt.h

Therefore, use UINTN for Gic Interrupt variables and use appropriate
typecasts wherever needed.
