tests: kernel: context: test k_cpu_idle for tickless kernel

Browse source 
We fix the kernel.context test, so it tests the
implementation of k_cpu_idle for tickless kernel.
As most platforms now support tickless kernel by
default, this extension of the test is essential
to get coverage on k_cpu_idle() API.
