Tracing: Enable tracing of ISR based on CONFIG_TRACING_ISR

In
https://github.com/zephyrproject-rtos/zephyr/blob/main/arch/arm/core/aarch32/isr_wrapper.S#L90
as well as in
https://github.com/zephyrproject-rtos/zephyr/blob/main/include/arch/arc/v2/irq.h#L93


`CONFIG_TRACING_ISR` is used, here `CONFIG_TRACING` is used. I believe
`CONFIG_TRACING_ISR` would be more correct.
