Add a test case that verifies that we can enumerate the SVE vector lengths on systems where we detect SVE, and that those SVE vector lengths are valid. This program was written by Dave Martin and adapted to kselftest by me.

KSelfTest ARM64 =============== - These tests are arm64 specific and so not built or run but just skipped completely when env-variable ARCH is found to be different than 'arm64' and `uname -m` reports other than 'aarch64'. - Holding true the above, ARM64 KSFT tests can be run within the KSelfTest framework using standard Linux top-level-makefile targets: $ make TARGETS=arm64 kselftest-clean $ make TARGETS=arm64 kselftest or $ make -C tools/testing/selftests TARGETS=arm64 \ INSTALL_PATH=<your-installation-path> install or, alternatively, only specific arm64/ subtargets can be picked: $ make -C tools/testing/selftests TARGETS=arm64 ARM64_SUBTARGETS="tags signal" \ INSTALL_PATH=<your-installation-path> install Further details on building and running KFST can be found in: Documentation/dev-tools/kselftest.rst
