Implement native StringView support for CharacterLength

Is your feature request related to a problem or challenge?

Part of #10918

Initial StringView is supported by #11667, which covers some most performance critical workloads, such as loading from parquet, reasonable aggregation, faster filtering etc. However, there are many operators not supported and using those operations will cause DataFusion to cast StringViewArray to StringArray, which is often unnecessary and slow.

Describe the solution you'd like

We should gradually implement native StringView support string operators, such as length, reverse, etc.

Here's a list of items to help implementing the support:

• Add Utf8View to the function signature, e.g., https://github.com/apache/datafusion/blob/main/datafusion/functions/src/unicode/character_length.rs#L46-L50

• Handle Utf8View in the invocation. The function likely already need to handle Utf8 and LargeUtf8, so we should just add a new case to the type match

• Write tests for the new Utf8View. As we now have three string types, it often need to restructure the test logic to reduce duplicated code.

• Make sure the test cases cover long (> 12 byte) and short strings.
