This commit brings power management subystem documentation up to date
with the implementation. The main changes since the last time the
documentation was updated include introduction of power managment
policies.

There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.
To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

This commit updates the documentation as follows:
- stresses that the lazy stacking preservation is disabled
by default and not supported in ARM Cortex-M builds,
- corrects the figure of extra stack requirement when
floating point services are enabled in ARM builds.

This commit provides the following fixes:
- Corrects the note regarding which ARM MCUs may support
floating point services
- Rewords the text stressing the undefined behavior when
multiple threads access the floating point registers.

Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all". This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.
This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)
This is a start to address issue #14313

Add framework for device Idle Power Management(IPM)
for suspending devices based on device idle. This will
help in saving power even while system(CPU) is active.
The framework uses device_set_power_state() API set the
device power state accordingly based on the usage count.

The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

The phrase 'low power state' is often incorrectly used to indicate
'low power' or 'deep sleep' states. This commit fixes the ambiguities
by renaming 'low power state' to 'power state' where necessary.

CPU_LPS_n name used to indicate a low power state is cryptic and
incorrect. The low power states act on the whole SoC and not exclusively
on the CPU. This patch renames CPU_LPS_n states to LOW_POWER_n. Also
HAS_ pattern for Kconfig options is used in favor of a non standard
_SUPPORTED. Naming of deep sleep states was adjusted accordingly.
Following is a detailed list of string replacements used:
s/SYS_POWER_STATE_CPU_LPS_(\d)_SUPPORTED/HAS_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_CPU_LPS_(\d)/SYS_POWER_STATE_LOW_POWER_$1/
s/SYS_POWER_STATE_DEEP_SLEEP_(\d)_SUPPORTED/HAS_STATE_DEEP_SLEEP_$1/
