What changes were proposed in this pull request?
Add shared JDBC type-mapping preflight validation for complete create and alter requests.
The shared operation layer now validates every type-bearing column or change before generating or executing DDL, and exposes capability hooks for connector-specific checks. Custom ClickHouse and OceanBase operation paths are routed through the same contract.
Why are the changes needed?
A later invalid column in a create or alter request must not leave earlier DDL partially applied. JDBC connectors need one shared boundary that converts or rejects the whole request before database mutation.
Fix: #12065
Related: #12056
Does this PR introduce any user-facing change?
Yes. Unsupported JDBC type mappings fail before DDL generation or execution, preserving the public invalid-argument and no-partial-mutation contract.
