Make `editor::AcceptPartialCopilotSuggestion` a deprecated alias (#35507)

This is consistent with there being no copilot expecific variant of
`editor::AcceptEditPrediction`. It also fixes a case where the
`disable_ai: true` has effects at init time that aren't undone when
changed, added in #35327.
