vim: Fix clipping when navigating over inlay hints (#22813)

This fixes the issue described in this comment:
https://github.com/zed-industries/zed/pull/22439#issuecomment-2563896422

Essentially, we'd clip in the wrong direction when there were multi-line
inlay hints.

It also fixes inline completions for non-Zeta-providers showing up in
normal mode.

Release Notes:
