PR description:

This PR makes some minor improvements to the Alpaka stand-alone and framework-based tests, that came up during the Alpaka tutorials on the 16-17 February:

• remove one leftover import from writer.py
• simplify getting the Device type from the Queue in AlpakaESTestData.h
• migrate the test modules from stream to global
• allocate host buffers in pinned memory accessible by the Platform devices in testKernel.dev.cc

PR validation:

All unit tests pass.

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:

Backport of #40808 to 13.0.x for consistency.
