## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
When I upgraded the df46, It was annoying for me to do the following thing(a
series of `downcast_ref`) and it's also easy to call the wrong method, such as
mixing `file_source()` and `data_source()`:
```rust
if let Some(scan_config) =
self.data_source().as_any().downcast_ref::<FileScanConfig>() {
if let Some(parquet_source) = scan_config
.file_source()
.as_any()
.downcast_ref::<ParquetSource>(){...}
```
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Add the `downcast_to_source` method for `DataSourceExec` to make life easy
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
Yes, I replace the existing code with the new method.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
