Fix CachingAllocator debug for non-async operations [14.0.x]

[fwyzard]

PR description:

@VinInn pointed out that filling memory asynchronously may be incorrect if the memory is later being set synchronously, without using a queue.
This is often the case with pinned host memory buffers, where the allocation and memset may be asynchronous, but the content is accessed directly using host-only operations.

This change makes the allocator wait for the memset to complete before returning the memory buffer to the user code.

It also adds a customisation function to activate memory filling, and uses it in the non-profling Alpaka workflows.

PR validation:

None, yet.

This pull request is fully signed and it will be integrated in one of the next CMSSW_14_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @rappoccio, @antoniovilela, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
