Alison Felizzi f795e7c0ec arm: New virtual PPI event fault type 
This commit introduces a new fault type, seL4_Fault_VPPIEvent.

This change means the kernel can reserve PPI interrupts and virtualise
them via delivering the irq to the active vcpu through a
specific fault. This enables multiplexing PPI IRQs across multiple VCPUS
which requires correctly masking and unmasking the IRQ depending on
which VCPU is running.

A new VCPU invocation, seL4_ARM_VCPU_AckVPPI is also added for
acknowledging the handling of the IRQ. This takes an IRQ as a parameter
but will only accept IRQ numbers that are sent as VPPIEvent faults.
