Migrate Unicode function to invoke_with_args #14709
Description
Is your feature request related to a problem or challenge?
As #14652, invoke_batch is deprecated. We should migrate all the UDFs to invoke_with_args. This issue would focus on the function in the datafusion/functions/src/unicode.
Describe the solution you'd like
- Remove invoke_batch for the function implementation and use implement invoke_with_args instead.
