tf-m: Implement os_wrapper_is_kernel_started

Browse source 
Implement the TF-M kernel-started hook (new in TF-M 2.3.0) using
xTaskGetSchedulerState(). Treat a suspended scheduler as started, since
the kernel has already been initialised.

Guard the hook with the same configuration condition as
xTaskGetSchedulerState() so configurations without that API continue
to build.
