fix: revert incorrect variadic parameter detection in DROP contexts - improves to 238/258 passing tests

- Removed isDropFunction logic that was incorrectly setting FUNC_PARAM_VARIADIC for anyarray parameters
- DROP FUNCTION contexts expect FUNC_PARAM_DEFAULT mode for all parameters
- Fixes polymorphism test that expects both text and anyarray parameters to have FUNC_PARAM_DEFAULT mode
