arm/efi: Enable runtime call flag checking
Define ARCH_EFI_IRQ_FLAGS_MASK for arm, which will enable the generic runtime wrapper code to detect when firmware erroneously modifies flags over a runtime services function call. We check all allocated flags, barring those which firmware has legitimate reason to modify (condition flags and IT state). While in practice corruption of some flags (e.g. J) would already be fatal, we include these for consistency and documentation purposes.
