312f1fa8 - [llvm][DebugInfo][test] DwarfTest: parameterize LanguageDescription tests (#162863)

[llvm][DebugInfo][test] DwarfTest: parameterize LanguageDescription tests (#162863) Better test coverage. The round-tripping test makes sure that if we ever change `llvm::dwarf::toDW_Lang` or `llvm::dwarf::toDW_LName`, we don't break the `LanguageDescription` API. The round-tripping test found an incorrect version check in `llvm::dwarf::toDW_Lang`, which I corrected as part of this PR (see the table at the bottom of https://dwarfstd.org/languages-v6.html for reference).
