GRANT and REVOKE ... ON FUNCTION and ON PROCEDURE kept the argument list as arg_types: Vec<DataType>, so an empty list and an absent one gave the same AST and GRANT EXECUTE ON FUNCTION f() TO bob printed back as GRANT EXECUTE ON FUNCTION f TO bob, which mean quite different things, as f() names the zero-argument overload, and a bare f is accepted only when no other function shares the name. Argument names and modes failed to parse, which breaks pg_dump output such as REVOKE ALL ON FUNCTION public.f(p_id uuid) FROM PUBLIC, and only one function was accepted per statement.

GrantObjects::Functions and GrantObjects::Procedures now hold Vec<FunctionDesc>, the type DROP FUNCTION and DROP PROCEDURE already use, and the parser reads them with the same parse_function_desc. They replace the Function and Procedure variants added for Snowflake in #1930, so this changes the public AST. Snowflake statements such as GRANT USAGE ON FUNCTION db1.sc1.foo(INT) TO ROLE role1 parse and print unchanged.
