Supermaven (#10788)

Adds a supermaven provider for completions. There are various other
refactors amidst this branch, primarily to make copilot no longer a
dependency of project as well as show LSP Logs for global LSPs like
copilot properly.

This feature is not enabled by default. We're going to seek to refine it
in the coming weeks.
