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.

The elf_parser library now generates a dot file with device dependencies
that can be later rendered using Graphviz. Each node in the diagram
contains the device label (taken from DT node). In some cases the label
property can be None, leading to build failures like:
```
line 273, in device_dependency_graph
text = '{:s}\\nOrdinal: {:d} | Handle: {:d}\\n{:s}'.format(
TypeError: unsupported format string passed to NoneType.__format__
```
This patch switches to node name instead, which will always be set to
some value. This value is actually what devices get now as a name if
they do not have a label set.

If a device manually specifies that it depends on a second DT device,
add the first device to the second devices list of supported devices.

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.

Adds a python module intended to simplify other scripts that need to
work with device information compiled into the first pass `.elf` file.
Scripts utilizing this module can focus on iterating over dependency
graphs to generate the desired output, instead of also needing to
extract and build the graphs in the first place.

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.
