tests: benchmarks: multicore: Add test for S2RAM and PPR

nordic-segl · rlubos · commit 7504e21df957 · 2024-11-13T11:32:58.000+01:00
Add non-functional check (current consumption) for sample
application that:
- runs on cpuapp, cpurad and cpuppr;
- enters low power state.

Confirm that when PPR core is used:
- SOC may enter low power states like IDLE or S2RAM.
