Add support for the CodeQL Query Language

[anticomputer]

This PR adds support for: https://github.com/tree-sitter/tree-sitter-ql

Note: passes tests and compiles cleanly. I've tested the resulting tree-sitter binary artifacts locally and they work as expected.

Is there already a ql-mode for Emacs? I couldn't find one.

[anticomputer]

Ah no there's not. I'm working on one which uses tree-sitter based highlighting, hence this PR, but it's not released yet.

If you prefer, we can just park this PR until the mode is publicly available and I'll revive it then, or we can remove this default association and just keep the upstream repo addition?

I've removed the default association to ql-mode for now in favor of being able to include the ql tree-sitter artifacts in tree-sitter-langs

Thanks!

This package currently provides queries only for tree-sitter-hl. Please remove non-hl queries.

Done :)

I've released a ql mode included with https://github.com/anticomputer/emacs-codeql, it is named ql-tree-sitter-mode, however I don't expect that to become a default association as it is not on MELPA yet. It would be great if we could include the tree-sitter-ql binary artifact as part of the tree-sitter-langs release though. If not possible, I'll continue packaging my own builds with the emacs-codeql package.
