Improve completer (#14004)

Browse Source 
This pr does two optimization for the completer:
- Switch `sort_by` to `sort_unstable_by` on `sort_completions` function
since it reduces memory allocation and the orders of the identical
completions are not matter.
- Change `prefix` type from `Vec<u8>` to `&[u8]` to reduce cloning and
memory.
