feat(sme): add basic SME2 tests
FEAT_SME2 introduces an architectural register ZT0 to support
lookup table feature. This patch ensures that EL3 has
properly enabled the SME2 for use at lower exception levels,
thereby disabling the traps execution at lower exception levels,
when instructions access ZT0 register to EL3.
