The k_stack data type cannot be u32_t on a 64-bit system as it is
often used to store pointers. Let's define a dedicated type for stack
data values, namely stack_data_t, which can be adjusted accordingly.
For now it is defined to uintptr_t which is the integer type large
enough to hold a pointer, meaning it is equivalent to u32_t on 32-bit
systems and u64_t on 64-bit systems.

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.

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

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.

* All .rst and additional required files are now copied from the doc/
folder into the build/rst folder using extract_content.py. The

and another into build/doc/rst) to manage relative paths.
