Now PSI already tracked workload pressure stall information for CPU, memory and IO. Apart from these, IRQ/SOFTIRQ could have obvious impact on some workload productivity, such as web service workload. When CONFIG_IRQ_TIME_ACCOUNTING, we can get IRQ/SOFTIRQ delta time from update_rq_clock_task(), in which we can record that delta to CPU curr task's cgroups as PSI_IRQ_FULL status. Note we don't use PSI_IRQ_SOME since IRQ/SOFTIRQ always happen in the current task on the CPU, make nothing productive could run even if it were runnable, so we only use PSI_IRQ_FULL.
