feat(emacs): Replace LSP-mode with eglot
LSP-mode in combination with the Rust language server does not really
work as RLS is extremely unstable.

This switches over to eglot, which automatically restarts RLS after
every crash. From initial testing it seems to be slightly less
annoying than the previous setup.
