@alamb, I think we could have a breaking change on `return_type` with
`ReturnTypeArgs`, and remove `return_type_from_exprs`.
```rust
fn return_type(&self, _args: ReturnTypeArgs) -> Result<DataType> {
struct ReturnTypeArgs<'a> {
args: &'a [Expr],
schema: &'a dyn ExprSchema,
arg_types: &'a [DataType],
}
```
Alternatively, we switch all the function to `return_type_from_exprs`, since
I think most of them would expect the same `nullable` from input.
