Reported by Hirally Santiago:

Current tickless idle implementation depends on the use of the SW ISR table for all interrupts. As a product developer, I may be interested in an application where parameterless ISRs are directly installed in the ISR vector table for performance or footprint reasons. Add support to Zephyr for this. This will probably take the form of macros that need to be put at the beginning and/or end of these special ISRs.

This's implementation re-work that should not change the apparent behavior of tickless idle @arc. Testability review mark as "NotTest", since the test case do not verify which way the implementation take.

Existing test cases will detect any regression/side-effect, if introduced by this re-work.

This appears to be an enhancement that is not a high priority at this time. I am removing this from the 1.5 queue.
