Review comment:
Still keep the original implementation. The reason is we fetch the RFW more
than one times at the `RuntimeFilterRecordBatch` side. If we remove it from the
`rfIdentifier2RFW` map, it will cause NPE.

> The current implementation of JPPD to find the probe side wrapper depends on
> the GroupScan's digest. But there's no promise the GroupScan's digest will
> not be changed since it is attached to the RuntimeFilterDef by different
> storage plugin implementation logic.So here we assign a unique identifier to
> the RuntimeFilter operator, and find the right probe side fragment wrapper by
> the runtime filter identifier at the RuntimeFilterRouter class.
