Use unique_xmalloc_ptr<char> when demangling
I noticed that some methods in language_defn could use unique_xmalloc_ptr<char> rather than a plain 'char *'. This patch implements this change, fixing up the fallout and changing gdb_demangle to also return this type. In one spot, std::string is used to simplify some related code, and in another, an auto_obstack is used to avoid manual management. Regression tested on x86-64 Fedora 34.
