pw_docgen: Fix paths, multiple sources
- Fix code for remapping paths into the docgen tree. Some path prefixes
were being incorrectly trimmed, preventing size report inclusion in
some cases.
- Make Sphinx warnings errors.
- Allow specifying multiple top-level sources to a pw_doc_gen.
- Move documentation for modules to their own table of contents.
- Rename module documentation to the module names.
