util/types, column, expressions: use types.Convert to replace Col.CastValue
...
The two methods has similar functionality and has complex logic, after this change,
the code base would be easier to maintain.
For `CAST` function, the behaviour is different than the general purpose `types.Convert`,
so I implemented a dedicated function for it.
