> Foundation for FLIP-568. Adds the validator and the {{@PublicEvolving}}
> connector API, no SQL surface yet.
> * {{StringUtf8Utils}} - new {{firstInvalidUtf8ByteIndex(byte[], int, int)}}
> validator (Flink-style branches reusing the existing {{decodeUTF8Strict}}
> algorithm).
> * {{EncodingUtils.isValidUtf8(byte[])}} / {{(byte[], int, int)}} - thin
> null-tolerant predicate delegating to the validator.
> * {{BinaryStringData.fromUtf8Bytes(byte[])}} / {{(byte[], int, int)}} -
> validating factory; returns {{null}} on null input (matches Spark's
> {{{}UTF8String.fromBytes{}}}), throws {{IllegalArgumentException}} with the
> byte index on invalid UTF-8.
> * {{StringData.fromUtf8Bytes}} - public-evolving interface methods that
> delegate.
