Some compilers and static analyzers warn when non-static (globals) are
not declared in some .h file. Tweak the generated code and add an
`extern` declaration before each device handle definition to make it
look it was declared in a (non-existent) .h file.
This makes the code a bit longer but it is already generated and very
repetitive anyway.
In the typical SOF configuration this silences about 150 sparse
warnings; as many as device handles.

An explicit import of edtlib is not required when using
pickle.load() and creates a duplicate module object.

Disables allowing the python argparse library from automatically
shortening command line arguments, this prevents issues whereby
a new command is added and code that wrongly uses the shortened
command of an existing argument which is the same as the new
command being added will silently change script behaviour.

Instead of hardcoding alignment size for pass 2 device handles, use
Z_DECL_ALIGN. This makes sure gen_handles.py is always in sync with the
type defined in device.h. The build assert in device.h can be removed as
a result, since we do not hardcode handles size anywhere else.

Replicate the devicetree dependencies into a sorted list. This ensures
that the structures added to the .__device_handles_pass2 section are
reproducible from build to build.
Tested with: west build -b native_posix tests/drivers/build_all/sensor
Without this change, two consecutive builds do not compare.

Output the final dependency graph as a `.dot` file, which when rendered
by graphviz can be easier to comprehend than the text descriptions.
This output is optional in that it will not be generated if `graphviz`
is not installed.

Use the new elf_parser module to simplify the process of generating the
final device handle arrays.

Rename the placeholder variable generated for PM slots so that the
prefix doesn't colide with the PM structs declared by devices. This
simplifies the process of searching for symbols in `.elf` files.

Move scripts needed by the build system and not designed to be run
individually or standalone into the build subfolder.
