SCORU/Node: Disable DAL if no DAL node configured
Context
The rollup node does not store any DAL related data if the DAL feature flag is disabled in the protocol. However it is enabled in Monadynet. This MR makes the rollup node not store any DAL data if there is no DAL node configured for it.
Fixes #4731 (closed).
Manually testing the MR
DAL data stored by the rollup node is large. To check run a rollup node with and without the DAL feature flag enabled. Their store directory should be of comparable size.
