devel/ctags-lsp: Add port

This is an LSP that uses universal-ctags, making it both
language-agnostic and compatible with the vast array of languages
that uctags can parse.

However, that also means that it's limited to the data in a tags file,
meaning things like tracking references is off the table. But, it is,
as the author notes, "better than nothing."

Instructions for enabling the LSP in Neovim and Helix can be found
