New version of Systemview has Zephyr API description that did not match
what we had, align with what the tools provides and expand hooks to
support additional APIs. We now cover most kernel APIs.

Adds generic trace hook macros for inserting trace hook for
function entry, exit, blocking, and object initialization
with a variable number of arguments (objects, return values,
etc.). Utilizing macro concatenation these macros produce
trace hooks of a similar format to the old trace system
with SYS_TRACING_OBJ_FUNC(k_thread, switched_in) being
turned into sys_trace_k_thread_switched_in() by the
preprocessor. Although these macros still rely on the manual
definition of each unique trace hook in tracing.h, the benefit
of not directly calling those is that we can enable/disable
trace hooks based on object type (k_thread, k_sem, etc.)
through the preprocessor while providing the ability of adding
type specific runtime trace processing similar to
SYS_TRACING_OBJ_INIT.

If Zephyr is running on a coprocessor we might lack I/O
such as uart or usb to output tracing datas but we might
have gigabytes of RAM available.
This patch allows to output trace datas to a ram buffer, which then
may be retrieved using gdb.
e.g:
(gdb) dump binary memory channel0_0 <ram_tracing_start> \
<ram_tracing_end>

Since the tracing of thread being switched in/out has the same
instrumentation points, we can roll the tracing function calls
into the one for thread stats gathering functions.
This avoids duplicating code to call another function.

MISRA-C Rule 5.3 states that identifiers in inner scope should

There is a global variable named "dev" to store which UART
device is being used the tracing backend. This name collides
with the parameter of same name in the ISR function. So rename

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

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.
