[LLDB] Unify DWARF section name matching (#141344)

Browse Source 
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.
