KVM: selftests: Use canonical $(ARCH) paths for KVM selftests directories
Use the kernel's canonical $(ARCH) paths instead of the raw target triple
for KVM selftests directories. KVM selftests are quite nearly the only
place in the entire kernel that using the target triple for directories,
tools/testing/selftests/drivers/s390x being the lone holdout.
Using the kernel's preferred nomenclature eliminates the minor, but
annoying, friction of having to translate to KVM's selftests directories,
e.g. for pattern matching, opening files, running selftests, etc.
Opportunsitically delete file comments that reference the full path of the
file, as they are obviously prone to becoming stale, and serve no known
purpose.

KVM: s390: selftests: Add regression tests for SORTL and DFLTCC CPU subfunctions
Introduce new regression tests to verify the ASM inline block in the SORTL
and DFLTCC CPU subfunctions for the s390x architecture. These tests ensure
that future changes to the ASM code are properly validated.
The test procedure:
1. Create a VM and request the KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute
from the KVM_S390_VM_CPU_MODEL group for this VM. This SUBFUNC attribute
contains the results of all CPU subfunction instructions.
2. For each tested subfunction (SORTL and DFLTCC), execute the
corresponding ASM instruction and capture the result array.
3. Perform a memory comparison between the results stored in the SUBFUNC
attribute (obtained in step 1) and the ASM instruction results (obtained
in step 2) for each tested subfunction.
This process ensures that the KVM implementation accurately reflects the
behavior of the actual CPU instructions for the tested subfunctions.
