KVM: arm64: selftests: Check the mandatory SMCCC_ARCH_FEATURES queries

tools/testing/selftests/kvm/arm64/hypercalls.c checks SMCCC_ARCH_FEATURES
with two expectations: hvc_info[] expects NOT_SUPPORTED with the
pseudo-firmware bitmaps cleared and something else with them set, and
false_hvc_info[] expects NOT_SUPPORTED for mismatched pairs. DEN0028H
7.3.6 mandates SUCCESS for arch_func_id SMCCC_VERSION and
SMCCC_ARCH_FEATURES itself, whatever the bitmaps hold, which neither
expectation allows.

Check those two in the feature-disabled and feature-enabled stages, so
the answer is asserted with the bitmaps cleared and again at their reset
values. They pass only with the preceding patch applied.
