As a followup of https://github.com/llvm/llvm-project/pull/67851, I'm defining a new namespace `lldb_plugin::dwarf` for the classes in this Plugins/SymbolFile/DWARF folder. This change is very NFC and helped me with exporting the necessary symbols for my out-of-tree language plugin. The only class that I didn't change is ClangDWARFASTParser, because that shouldn't be in the same namespace as the generic language-agnostic dwarf parser. It would be a good idea if other plugins follow the same namespace scheme.
