hw/intc/arm_gicv3: Add new gicv3_intid_is_special() function
The GICv3/v4 pseudocode has a function IsSpecial() which returns true if passed a "special" interrupt ID number (anything between 1020 and 1023 inclusive). We open-code this condition in a couple of places, so abstract it out into a new function gicv3_intid_is_special().
