Add CI testing for ArmPL backend

Add CI testing for ArmPL backend using the
GitHub runner ubuntu-24.04-arm. Keep the CI
strategy in line with the existing x86_64 pipeline
splitting the jobs by domain.

There is no DPC++ release for aarch64 host, so the
CI job builds it from source and caches. The build
takes a lot of resources, but should almost always
be loaded from the cache.

DPC++ tag nightly-2025-04-01 is used instead of the
latest release v6.0.0 because the release was not
compatible with the new-ish aarch64 glibc installed
on the runner. This was fixed (presumably through
upstream LLVM) later. We can move to the next
open-source release once it becomes available.
