Use explicit acelerator types in alpaka tests [14.0.x]

[fwyzard]

PR description:

Update the HeterogeneousTest alpaka tests to use the explicit accelerator types in alpaka device code:

• move all alpaka device code to the ALPAKA_ACCELERATOR_NAMESPACE namespace;
• use the explicit accelerator types, like Acc1D or Acc2D, instead of the generic TAcc template argument.

PR validation:

The HeterogeneousTest unit tests pass:

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. @antoniovilela, @sextonkennedy, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
