Refactor the binary import and dependency resolution infrastructure to support multiple platforms (Linux, Windows, macOS) via a configuration-driven root system. Major changes: * Overhaul PDB and DWARF importers for platform-aware debug info loading. * Refactor LDDTree into a template-based architecture with platform-specific implementations (ELF, PE/COFF). * Mostly rewrite the PDB importer, which had significant limitations.
