ECAL - Add integrity checks for strip and xtal ids to GPU unpacker - 131X #41981

PR description:

This PR adds integrity checks for strip ID and xtal ID to the GPU unpacker similar to the ones that exist in the CPU unpacker. This avoids crashes like the ones reported in #39568

For events with data corruption in a tower a difference in the number of unpacked digis can occur between the CPU unpacker and the GPU one because the former stops unpacking the tower if an inconsistency is detected in one channel, whereas the later unpacks the channels in parallel and an inconsistency in one channel does not affect the unpacking in other threads.
In many cases, however, an integrity problem in the raw data affects most of the channels in the tower. From the three instances reported in #39568 this year only one resulted in a difference of one digi being produced after the fix.

PR validation:

Backport of #41977 for HLT to avoid crashes when encountering invalid detector IDs in the raw data.

This pull request is fully signed and it will be integrated in one of the next CMSSW_13_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_13_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
