Add a call to get the system tick count as an official API (and
redefine the existing millisecond API in terms of it). Sophisticated
applications need to be able to count ticks directly, and the newer
timeout API supports that. Uptime should too, for symmetry.

Add tick-based (i.e. precision resistant) inspection APIs for kernel
timeouts visible via k_timer, k_delayed work and thread timeouts
(i.e. pended/sleeping threads). These are each available in
"remaining" and "expires" variants returning time values relative to
current time and system start. All have system calls where applicable
(i.e. everywhere but k_delayed_work, which is not a userspace API)
The pre-existing millisecond "remaining_get()" predicates for timer
and delayed work remain, but are expressed in terms of the newer
calls.

Add support for "absolute" timeouts, which are expressed relative to
system uptime instead of deltas from current time. These allow for
more race-resistant code to be written by allowing application code to
do a single timeout computation, once, and then reuse the timeout
value even if the thread wakes up and needs to suspend again later.

Add a CONFIG_TIMEOUT_64BIT kconfig that, when selected, makes the
k_ticks_t used in timeout computations pervasively 64 bit. This will
allow much longer timeouts and much faster (i.e. more precise) tick
rates. It also enables the use of absolute (not delta) timeouts in an
upcoming commit.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

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.

In the current implementation both SPSR and ELR registers are saved with
the callee-saved registers and restored by the context-switch routine.
To support nested IRQs we have to save those on the stack when entering
and exiting from an ISR.
Since the values are now carried on the stack we can now add those to
the ESF and the initial stack and take care to restore them for new
threads using the new thread wrapper routine.

Such state needs to be set _from_ the PM API functions and not the other
way round. So if a network device driver does not support such API, it
will not be able to set the core net_if on PM state, obviously.
Currently, these functions only set/unset NET_IF_SUSPENDED flag.
More logic will be added later, to decide whether the net_if can be
actually set to suspend mode or not and also to take care of all timers
related to the interface.

This commit renames the `cortex_r` directory under the AArch32 to
`cortex_a_r`, in preparation for the AArch32 Cortex-A support.
The rationale for this renaming is that the Cortex-A and Cortex-R share
the same base design and the difference between them, other than the
MPU vs. MMU, is minimal.
Since most of the architecture port code and configurations will be
shared between the Cortex-A and Cortex-R architectures, it is
advantageous to have them together in the same directory.
