[FLINK-39206][jdbc] Give each split reader its own connection provider

JdbcSource handed the same JdbcConnectionProvider to every split reader it
created, while flink-connector-base builds a split reader per split fetcher and
closes the reader of a finished split while the reader of the next split is
already reading. A provider holds a single connection and is not thread safe,
so the finished reader closed the running reader's result set and the job
failed instead of finishing.

Copy the provider per split reader, the way other connectors give each split
reader its own client. A reader now owns its copy, so it closes the result set,
the connection and the provider together, and the interface says that it is
copied.
