tests: benchmarks: multicore: idle_wdt: Add test on APP core only

Add test configuration where WDT is tested on APP core only.

Allow comparison of current consumption in low power states when WDT
is running in APP domain only or in both APP and Radio domains.

Define sysbuild Kconfig that controls core synchronization in
both sub-images.
