CALCITE-7845

Changes Proposed

Fix UDF/UDTF overload resolution when concrete parameter types coexist with Object (ANY). Prefer compatible concrete overloads and use Object as a fallback, avoiding assertion failures regardless of registration order.
For overloads foo(String), foo(Timestamp), and foo(Object):

SELECT foo('text');                          -- String
SELECT foo(TIMESTAMP '2024-01-02 03:04:05');  -- Timestamp
SELECT foo(TRUE);                            -- Object
