AlpakaServiceSerialSync should always be available

[fwyzard]

PR description:

The AlpakaServiceSerialSync should always be available, even if the "cpu" accelerator is not listed in process.options.accelerators.

PR validation:

The workflows 141.044407 and 141.044483 were failing due to the missing AlpakaServiceSerialSync in step3.
With these changes they run successfully.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

To be backported to 15.0.x for data taking.

[fwyzard]

please test

[fwyzard]

141.044407 and 141.044483 fail in the GPU IBs because they don't find the alpaka_serial_sync::AlpakaService for the GPU-only workflows.

These changes should fix that.

CUDA Comparison Summary

There are some workflows for which there are errors in the baseline:
141.044407 step 3
141.044483 step 2
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request

This pull request is fully signed and it will be integrated in one of the next master IBs (but tests are reportedly failing). This pull request will now be reviewed by the release team before it's merged. @mandrenguyen, @antoniovilela, @sextonkennedy, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
