refactor!: remove lsp_util (nvim 0.9.0 compatibility)

BREAKING CHANGE: This commit removes the `lsp_util` module, which was
used to provide compatibility with Neovim 0.9.0. We now only support
nvim 0.10.0 and later.

This was announced before, but I forgot to use `!` in the commit message.

This is probably the first breaking change for nvim 0.9.0.
