Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

Move to using PRIu64/PRId64 instead of %llu/%lld since on
native_posix_64 the uint64_t/int64_t type is defined in terms of 'long
int' and not 'long long int'.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

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_thread_create and K_THREAD_DEFINE to use the standard timeout
macros.

Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.
Turn it on pervasively. Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests
that can be independently run in an otherwise SMP environment, and via
setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

"50" ticks is fine with 100 Hz timer precision but way too short to
survive the conversion to milliseconds on fast, non-decimal tick
rates. Make it half a second, which was the original intent.

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 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.

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.

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.
