Integrate DWARF plugin into SCTK release and correct documentation

[johnmhoran]

We evidently have a plugin to collect certain information related to DWARF references. See, e.g., the SCTK RTD. I tested these instructions yesterday using 21.2.9, with this result: Error: no such option: --dwarf.

It appears that the plugin exists only in a branch and is not packaged in PyPI. See, e.g.,

https://github.com/nexB/scancode-plugins/tree/develop/binary-analysis/scancode-compiledcode

https://github.com/nexB/scancode-plugins/tree/develop/binary-analysis

It would be useful to be able to test it in a release (including whether it works with Python 3), and to update the RTD documentation to provide a complete and accurate description of how to run the plugin so it can be tested (and, if it works as desired, used).

I forgot to update the ticket but I have pushed https://pypi.org/project/compiledcode/ this summer...
So you can try to get the latest scancode and then pip install compiledcode on top in its activated virtualenv ... This is not fully tested yet.

Update from Chin Yeung from 3/30/22 from Issue 2902. I closed 2902 in favor of tracking this Issue.
There are two issues that I spot for the --dwarf plugin:

Nothing is returned from the --csv output (Note that the --json and --yaml work fine)
The returned dwarf reference path is not normalized (i.e. there are some path that have project/a/b/c/../../test.c)

How To Reproduce
scancode --dwarf <project> --csv output.csv
