ANDROID: tracing: Add restricted vendor hooks for preemptirq events

We have debug infrastructure built on top of preempt/irq disable/enable
events. This requires modifications to the kernel tracing code. Since
this is not feasible with GKI, we started with registering to the
existing preemptirq trace events. However the performance of wide
variety of use cases are regressed as the rate of preemptirq events
is super high and generic trace events are slow.

Since GKI allows optimized trace events via restricted trace hooks,
add the same for preemptirq event.
