Grants for user doesn't show privilege info for bindings. But we have checked permission for users to create bindings.

研究方向
Investigate the current implementation of SHOW GRANTS in TiDB, specifically in the privilege package. Look for how bindings privileges are checked (e.g., in `server/privilege/` or `planner/core/`). Examine the privilege check for creating bindings and see why it's not reflected in SHOW GRANTS. The fix likely involves adding the binding privilege information to the grants output, referencing existing patterns for other privileges.
