Review Comment:
For those tableSourceSpec that points to the same source, will they have the
same `ScanTableSource.ScanRuntimeProvider provider` instance?
If yes, instead of adding an extra interface `WithSourceInfo` to maintain
the source table identifier in selected Transformation subclass, would it be
more intuitive to have the same instance of `ScanRuntimeProvider` always return
the same Transformation, similar to what is done for
`TransformationScanProvider`?
