Make @Sql work with R2DBC where no DataSource available

[mipo256]

Currently, if the application does not have the DataSource/PlatofrmTransactionManager in the context, then the usage of @Sql in tests is impossible:

But in case the application is working with spring-data-r2dbc, we neither have the DataSource, nor the PlatofrmTransactionManager. So it would be great if the @Sql could be used with spring-data-r2dbc.
