This command is useful for signing binaries for loading by a
bootloader. At present, only MCUboot's "imgtool" is supported, but it
would be straightforward to add support for additional tools.
Using this command instead of "plain" imgtool avoids looking up any
numbers for the flash write block size, text section offset, or slot
size to get a signed binary. All users need to specify is the location
of the signing key.
This greatly improves usability for those unfamiliar with MCUboot, or
even experienced users who have to deal with multiple flash partition
layouts, boards, etc.
The command works by inspecting state in the Zephyr build system, some
of which is also provided by the runner package.

Although each of these command implementations has good output for
"west <command> --help", the "west --help" output is missing the
one-line descriptions.
Add them by modifying west-commands.yml to use a new 'help' key in
each command name. These need to be kept in sync with the Python
sources. For now just do that by copy/pasting. We could add fancy
logic to load the help from west-commands.yml later if we want.

West now supports a mechanism for extension commands. Use it to move
the command implementations that are tightly coupled with boards and
the zephyr build system back into the Zephyr repository.
This patch doesn't include test cases. Those will be moved over in a
subsequent patch.
