We are now in the process of extracting edtlib and dtlib into a
standalone source code library that we intend to share with other
projects.
Links related to the work making this standalone:
https://pypi.org/project/devicetree/https://python-devicetree.readthedocs.io/en/latest/https://github.com/zephyrproject-rtos/python-devicetree
This standalone repo includes the same features as what we have in
Zephyr, but in its own 'devicetree' python package with PyPI
integration, etc.
To avoid making this a hard fork, move the code that's being made
standalone around in Zephyr into a new scripts/dts/python-devicetree
subdirectory, and handle the package and sys.path changes in the
various places in the tree that use it.
From now on, it will be possible to update the standalone repository
by just recursively copying scripts/dts/python-devicetree's contents
into it and committing the results.
This is an interim step; do NOT 'pip install devicetree' yet.
The code in the zephyr repository is still the canonical location.
(In the long term, people will get the devicetree package from PyPI
just like they do the 'yaml' package today, but that won't happen for
the foreseeable future.)
This commit is purely intended to avoid a hard fork for the standalone
code, and no functional changes besides the package structure and
location of the code itself are expected.

The script gen_handles.py was introduce in #32127 but relies on
ZEPHYR_BASE being set in environment.
However, it is not a requirement to set Zephyr base in the users
environment, therefore this is changed to an argument `-z` or
`--zephyr-base` which will be passed from the build system to the
script.
If `-z` or `--zephyr-base` is not provided, the environment will be
checked for a ZEPHYR_BASE setting there.

Following the idiom used for system calls, add script support to read
the initial application binary to identify which devices are defined,
and to use their offset in the device array as their unique handle
rather than the externally-defined ordinal from devicetree. The
device dependency arrays are updated to use these handles.
