Rémi Verschelde 1039ba9ffb EditorSettings: Remove enable_code_completion_delay 
It was badly named (it disables code completion, not just the delay), and also
badly implemented (not preventing the timer for running, but just preventing it
to show the autocompletion).

It could be readded with a proper name and cleaner implementation if there's an
actual need for it.

Supersedes #24407 and closes #24352.
