Remove legacy CUDA modules for HCAL unpacking and local reconstruction [15.0.x]

[fwyzard]

PR description:

Remove legacy CUDA modules for HCAL local reconstruction.
The alpaka version has been commissioned and used in production.

Remove legacy CUDA modules for HCAL unpacker.
The outcome of the discussion with the HCAL DPG is that:

• for Run 3 we should use the legacy cpu unpacker, and the alpaka version of the legacy-to-SoA converter;
• for Phase 2 the decision can be revisited once the final raw and digi formats are defined.

PR validation:

None.

If this PR is a backport please specify the original PR and why you need to backport that PR.

Backport of #46004 to 15.0.x to clean up the code base.

This pull request is fully signed and it will be integrated in one of the next CMSSW_15_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_15_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @mandrenguyen, @rappoccio, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
