Currently, drgn_language_from_die() returns the default language when it encounters an unknown DW_LANG because the dwarf_info_cache always wants a language. The next change will want to detect the unknown language case, so make drgn_language_from_die() return NULL if the language is unknown, move it to language.c, and fold drgn_language_from_dw_lang() into it.
