feat: Add custom completer for `cargo help <TAB>` ### What does this PR try to resolve? Tracking issue #14520 Add custom completer for `cargo help <TAB>` ### Additional information The current completer function is quite slow because it executes too many functions. One idea I have is to use the file!() macro to list the filenames under the commands directory, excluding mod.rs, and return them as the completion results. Would this approach be too hacky?

Add custom completer for

The current completer function is quite slow because it executes too many functions. One idea I have is to use the file!() macro to list the filenames under the commands directory, excluding mod.rs, and return them as the completion results. Would this approach be too hacky?
