Different object file formats support DWARF sections (COFF, ELF, MachO, PE/COFF, WASM). COFF and PE/COFF only matched a subset. This caused some GCC executables produced on MinGW to have issue later on when debugging. One example is that `.debug_rnglists` was not matched, which caused range-extraction to fail when printing a backtrace. This unifies the parsing of section names in `ObjectFile::GetDWARFSectionTypeFromName`, so all file formats can use the same naming convention. Since the prefixes are different, `GetDWARFSectionTypeFromName` only matches the suffixes (i.e. `.debug_` needs to be stripped before). I added two tests to ensure the sections are correctly identified on Windows executables.
