[I] Optimize `left`, `right` to avoid copying for `Utf8`, `LargeUtf8` input [datafusion]
neilconway opened a new issue, #21441:
URL: https://github.com/apache/datafusion/issues/21441
### Is your feature request related to a problem or challenge?
We currently avoid copying for `Utf8View` input, but we always copy for other string input types. If we changed `left` and `right` to always return `Utf8View` (a la `substr`), we could be zero-copy for the other string input types as well.
