Dmitrii Golovanov 9c7288e86e arch: common: timing: Fix timing cycles 32bit rollover
Fix `arch_timing_cycles_get()` to prevent overflow on 32bit cycles
rollover. Also make `arch_timing_counter_get()` to work 64bit when
`CONFIG_TIMER_HAS_64BIT_CYCLE_COUNTER` is set.

The issue was observable, for example when `tests/benchmarks/wait_queues`
or `tests/benchmarks/sched_queues` were executed on qemu for `mps2/an385`
and the benchmark has its iterations large enough as the default
BENCHMARK_NUM_ITERATIONS=1000.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
