Introduce ProjectConf module to cleanly parse make/project.conf ini-like
configuration files. The new class supports:
- ini-style sections with header comments
- Key-value pairs with backslash line continuation
- Quoted values preserving spaces and comment delimiters (#) inside
- Inline comments outside of quotes
- Comma-separated list values with quoted commas
- Cached section parsing to avoid re-parsing the same section
- .get_section() to return an entire section unparsed
