Enhance the example-application repository with a configurable,
trivial library example and associated test cases.
.
This implementation appears to make no assumptions.
.
This implementation was verified by running the following commands
in an example-application workspace and verifying all tests passed.
1. `west build -b native_posix -p always example-application/tests/lib/custom_lib/`
2. `./build/zephyr/zephyr.exe`
3. `west build -b native_posix -p always example-application/tests/lib/custom_lib/ -- -DCONFIG_CUSTOM_LIB_GET_VALUE_DEFAULT=6`
4. `./build/zephyr/zephyr.exe`
5. `zephyr/scripts/twister -T example-application/tests/ \
-p qemu_cortex_m0`
6. `cd zephyr/doc && make clean && make` built cleanly.
.
Note that `twister` does not follow the `zephyr/module.yml:tests`
setting to discover tests in modules, so the testcase-root must be
explicitly provided.

Create lib subsystem with empty Kconfig menu, subsystem build file.
Updated top-level build and documentation to include subsystem.
This was created to provide an example of how the `lib/` directory
can be connected to the Zephyr build system through `module.yml`,
and so that CI can verify that the extension settings used here
work with these sub-trees.
.
The approach follows the pattern of paralleling the Zephyr tree.
An empty subsystem was implemented rather than a non-empty one
in order to isolate the core changes from any specific library.
This provides a clean reference for users.
.
It was assumed that some users will want to strip out the `lib/`
subsystem separate from existing subsystems, and vice versa.
.
This was verified by:
- visually verifying a clean build of:
`west build -b custom_plank -p always example-application/app/`
- visually verifying the subsystem appeared in the correct
location in a clean build of:
`west build -b custom_plank -p always example-application/app/`

Add a working example for how to implement a west command within the
user's manifest repository. There is documentation for this, but we
should have some working code in here just to make life easier for
people.

With the recent changes in how Kconfig options are enabled using DT
helpers, using select leads to a better/more scalable pattern. Each
driver Kconfig option is expected to select its dependencies now.

The option is no longer needed, zephyr,examplesensor driver will
automatically be selected based on DT (and because we enable all of its
dependencies, including CONFIG_SENSOR).

Make zephyr,examplesensor driver option dependent on it being defined in
Kconfig and set its default based on DT status as well.

-s/--source is a legacy option. There's a proposal to actually use it
for something else in Zephyr now:

Zephyr includes are now prefixed with <zephyr/...>. While the old path
can still be used when CONFIG_LEGACY_INCLUDE_PATH=y, it's better to be
prepared for the future.

Fixes: #39270
The latest zephyrprojectrtos/ci no longer sets ZEPHYR_SDK_INSTALL_DIR
in the environment and doesn't register the Zephyr-SDK as a CMake
package in the CMake package registry.
To ensure the the Zephyr SDK can be correctly discovered by
find_package(Zephyr-sdk) we add `/opt/toolchains` to the
CMAKE_PREFIX_PATH environment variable which is a list containing
additional search prefixes for the `find_package()` function.

The initial idea behind this code was to showcase documentation. It does
not add any special value to the sample, so remove it. A proper library
can be added in the future.

Use the recently introduced GPIO API that allows obtaining pin state

Provide an overlay to shows how to run the example-application on boards
that are part of the Zephyr tree. Sometimes initial development is
performed on dev-kits, so it can be useful. A different vendor than the
one used for the custom board (Nordic) has been chosen to show
application portability.
