[FLINK-15804] Support the new type inference in Scala Table API scalar functions

• Type: Sub-task
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 1.14.0
• Component/s: Table SQL / API
• Labels: auto-unassigned pull-request-available

Release Note

Scalar functions that are called using Scala implicit conversions have been updated to use the new type system and new type inference. Users are requested to update their UDFs or use the deprecated `TableEnvironment.registerFunction` to restore the old behavior temporarily by calling the function via name.

Description

Currently, we cannot distinguish between old and new type inference for Scala Table API because those functions are not registered in a catalog but are used "inline". We should support them as well.
