feat(sme): update sme/mortlach tests
FEAT_SME is an optional architectural extension from v9.2.
Previously due to the lack of support in toolchain, testing
SME instructions were overlooked and minimal tests were added.
This patch addresses them, with additional tests to test
the SME instructions. In order to avoid toolchain requirements
we manually encode the instructions for accessing ZA array.
