Add Support for Well-Known Protobuf Types in Protobuf Format

Why it matters

This feature enables ClickHouse to properly recognize and handle Google's well-known Protobuf types, improving compatibility and ease of use when working with Protobuf-encoded data. It solves the problem of limited support for these standard types, allowing users to efficiently parse and query data that relies on commonly used Protobuf message types.

How to use it

To use this feature, specify the Protobuf format when importing or exporting data with well-known Protobuf types. Ensure your Protobuf schema includes references to the standard well-known types as defined by Google. No additional configuration is required; ClickHouse will automatically support these types during Protobuf data processing.
