[FAB-9204] new proto for transient store entry

In the current code, the transient store persists rwset.TxPvtReadWriteSet
as a value. This CR defines a new proto message in the `transientstore`
package named `TxPvtReadWriteSetWithConfigInfo` which encapsulates
rwset.TxPvtReadWriteSet and common.CollectionConfigPackage

Gossip will utilize this new proto message while supporting
dissemination with dynamic collections.
