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.
