Subject: [PATCH 1/2] build and install tree-sitter parsers

neovim needs a number of prebuilt parsers in <prefix>/lib/nvim/parser/
or else it will throw errors when opening e.g. ":help".
USE_BUNDLED is also not a valid option for the root cmake build system
anymore, but applies to the one in cmake.deps/.
