nvim: Add copilot suggestions to blink

Suggestions are given at the top of the completion menu. Additionally,
since that can get really annoying really quick there have been some
changes specifically for copilot.lua:

We start with it disabled. It can be enabled with `<leader>ap` and
disabled again with `<leader>aP` for Ai>coPilot. If the plugin at some
point exposes functionality to toggle itself on/off completely I would
gladly switch to that. The current toggle command only attaches/detaches
the buffer but still runs the client in the background. This is less
desirable for me, plus it means the completions are still done
automatically in blink.
