feat!: drop makefile support, norg parser

Norg install_info and queries are maintained by neorg.

All other parsers are compatible with C++11, so fix that as standard.
(Can be bumped if all supported platforms support C++14.)

Remove Makefile support, as it's no longer needed.

 You can also skip step 2 and use `:TSInstallFromGrammar zimbu` to install directly from a `grammar.js` in the top-level directory specified by `url`.
 Once the parser is installed, you can update it (from the latest revision of the `main` branch if `url` is a Github repository) with `:TSUpdate zimbu`.
 
+**Note:** Parsers using external scanner need to be written in C. C++ scanners are no longer supported.
