This patch adds llvm::codeview::SourceLanguage entries, DWARF translations, and PDB source file extensions in LLVM and allow LLDB's PDB parsers to recognize them correctly.

The CV_CFL_LANG enum in the Visual Studio 2022 documentation https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang defines:

  CV_CFL_OBJC     = 0x11,
  CV_CFL_OBJCXX   = 0x12,

Since the initial commit in D24317 <https://reviews.llvm.org/D24317>, ObjC was emitted as C language and ObjC++ as Masm.
