This will be used in subsequent patches when adding commands that
interface with the runner package. These need to do things like
ensuring the CMake build is up to date, parsing the cache, etc.
To keep that interface clean, provide this functionality in a separate
module.

We have agreed to develop a meta-tool named "west", which will be a
swiss-army knife of Zephyr development. It will support use cases like
building, flashing and debugging; bootloader integration; emulator
support; and integration with multiple git repositories.
The basic usage for the tool is similar to git(1):
west [common opts] <command-name> [command opts] [<command args>]
There are common options, such as verbosity control, followed by a
mandatory sub-command. The sub-command then takes its own options and
arguments.
This patch adds the basic framework for this tool, as follows:
- a Python 3 package named 'west'. There is no PyPI
integration for now; the tool will be improving quickly, so we need
to keep users up to date by having it in tree.
- an main entry point, main.py, and a package-level shim, __main__.py
- a cmd subpackage, which defines the abstract base class for commands
- logging (log.py)
- catch-all utilities (util.py)
Windows and Unix launchers so users can type "west" to run the tool
after sourcing the appropriate zephyr-env script for their
environment are in the Zephyr tree.
Subsequent patches will start to add individual commands.
