ECAL - Add dummy collections to ECAL GPU unpacker

[thomreis]

PR description:

Adds dummy collections to the EcalCPUDigisProducer module, which produces the ecalDigis collections in the cuda branch of the SwitchProducerCUDA.
Not having the collections produced resulted in floods of warning messages about missing EcalRawData collections in the ECAL DQM monitoring task.

It is planned that the GPU unpacker will unpack the auxiliary collections in the future, replacing the dummy collections with properly filled ones.

This PR addresses part of #42720 .

PR validation:

WF 12434.512 does not show the warning messages anymore.
