LanguageServers: Rename AutoCompleteEngine => CodeComprehensionEngine

This feels like a better name since the "autocomplete engine" can, in addition to providing autocomplete suggestions, also find declarations of symbols and report back the symbols that are defined in a document. Also, Cpp/ParserAutoComplete has been renamed to CppComprehensionEngine and Shell/AutoComplete has been renamed to ShellComprehensionEngine.
