Add input_format_csv_use_default_on_bad_values setting for default value on CSV parsing errors

Why it matters

This feature allows users to handle CSV import errors more gracefully by substituting default values instead of failing the entire row or query when a field contains invalid data. It improves data ingestion robustness and minimizes import interruptions due to bad field values.

How to use it

To enable this feature, set the input_format_csv_use_default_on_bad_values setting to true when importing CSV data. This can be done by specifying the setting in the query or in the client configuration. When enabled, ClickHouse will insert default values for fields that cannot be parsed instead of raising an error.
