perfetto/ftrace: Introduce rpm_status ftrace event

The tracepoint is introduced in 5.15+ Android Common Kernels.

This event logs the runtime power state value of a Linux device (device
in this context is any hardware component managed by a Linux kernel
driver) whenever it changes. This is useful for providing granular
tracking of runtime power state transitions.
