b2e4283555 sys_clock: Make sys_clock_hw_cycles_per_tick() a proper API
This was another "global variable" API.  Give it function syntax too.
Also add a warning, because on nRF devices (at least) the cycle clock
runs in kHz and is too slow to give a precise answer here.

91fe22ec7d kernel: Improve tick <-> ms conversion.
The kernel incorrectly assumed, that system timer frequency is always
divisible without remainder by couple "natural" tick rates (like 100).
As result on some SoCs, time calculations was not correct, producing
strange effects (invalid sleep times, incorrect k_uptime_get() etc.).

This commit enables accurate, but costly (using 64-bit math) tick <-> ms
conversion if the selected tick interval is not exact due to hardware
limitations.

Also, this commit fixes tests in which removed _ms_per_tick were used.

540e11ced7 tests: rename main test to main.c
For many tests, avoid splitting into files and put eveything in main.c.
For many of the tests, use main.c as the test source file to keep things
consistent.

2a44e8ea4d tests: kernel: Add a test to verify early sleep
Add a test to verify that k_sleep() can be used to put
the calling thread to sleep for a specified number of
ticks during system initialization.

This test is inspired from legacy test_early_sleep test
from v1.7.0 release.
