Mark the old time conversion APIs deprecated, leave compatibility
macros in place, and replace all usage with the new API.

Re-run with updated script to convert integer literal delay arguments to
k_sleep to use the standard timeout macros.

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.

The existing API defined sys_clock_{hw_cycles,ticks}_per_sec as simple
"variables" to be shared, except that they were only real storage in
certain modes (the HPET driver, basically) and everywhere else they
were a build constant.
Properly, these should be an API defined by the timer driver (who
controls those rates) and consumed by the clock subsystem. So give
them function syntax as a stepping stone to get there.
Note that this also removes the deprecated variable
_sys_clock_us_per_tick rather than give it the same treatment.

On some architectures tick time cannot be expressed as integer
number of microseconds, introducing error in calculations using
sys_clock_us_per_tick variable.
This commit deprecates the sys_clock_us_per_tick variable and
replaces its usage by more precise calculations based on
sys_clock_hw_cycles_per_sec and sys_clock_ticks_per_sec.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

k_cycle_get_32() needs to return a monotonically increasing value,
except in cases of 32-bit integer overflow. Enforce this with a
test case.
We also check that the number of cycles elapsed after sleeping for 1
second is at the expected value. This can help catch errors on platforms
that use different timer sources for the system clock and timestamps.
This test case adapted from some code provided by Sergey Arkhipov
when troubleshooting ZEP-1546.
