arch_interface.h is for architecture and should not be
under sys/. So move it under include/zephyr/arch/.

Move runtime checks to use arch_num_cpus() and build checks
to use CONFIG_MP_MAX_NUM_CPUS. This is to allow runtime
determination of the number of CPUs in the future.

Simple tests to check the sanity of implementations. As with any tests
involving time, a constant "tolerance" of 10% is used in some of the
measurements.
Checks are basically answering the questions 1) "is time always
increasing?" and 2) "at a somewhat constant pace?". And some tests for
the time conversion, answering "is the elapsed time in nanoseconds
somewhat coherent?".
As timing and emulation are a somewhat dangerous combination,
`testcase.yaml` exclude CONFIG_QEMU_TARGET=y from tests.
