Subject: [PATCH] [LLDB][NFC] Create a namespace for the DWARF plugin

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 two classes that I didn't change are DWARFDataExtractor, because that's being explicitly exported as part of lldb_private in `lldb-forward.h` , and the ClangDWARFASTParser, because that shouldn't be in the same namespace as the generic language-agnostic dwarf parser, but I'm okay with changing that. In any case, even if I didn't need this for my work, adding this namespace could be considered a good practice.
