genirq/timings: Add selftest for circular array
Due to the complexity of the code and the difficulty to debug it, add some
selftests to the framework in order to spot issues or regression at boot
time when the runtime testing is enabled for this subsystem.
This tests the circular buffer at the limits and validates:
- the encoding / decoding of the values
- the macro to browse the irq timings circular buffer
- the function to push data in the circular buffer
