that separates out language and version. To avoid reinventing the wheel and introducing subtle incompatibilities, this API uses the table of languages and versiond defined by the upcoming DWARF 6 standard (https://dwarfstd.org/languages-v6.html). While the DWARF 6 spec is not finialized, the list of languages is broadly considered stable. The primary motivation for this is to allow the Swift language plugin to switch between language dialects between, e.g., Swift 5.9 and 6.0 with out introducing a ton of new language codes. On the main branch this change is considered NFC. Depends on https://github.com/llvm/llvm-project/pull/89980
