KVM: arm64: Introduce set_direct_injection irq_op
GICv5 adds support for directly injected PPIs. The mechanism for
setting this up is GICv5 specific, so rather than adding
GICv5-specific code to the common vgic code, we introduce a new
irq_op.
This new irq_op is intended to be used to enable or disable direct
injection for interrupts that support it. As it is an irq_op, it has
no effect unless explicitly populated in the irq_ops structure for a
particular interrupt. The usage is demonstracted in the subsequent
change.
