KVM: arm64: selftests: Ensure pending interrupts are handled in arch_timer test

Break up the asm instructions poking daifclr and daifset to handle interrupts. R_RBZYL specifies pending interrupts will be handle after context synchronization events such as an ISB. Introduce a function wrapper for the WFI instruction.
