tests/functional/aarch64: add tests for FEAT_RME

This boot an OP-TEE environment, and launch a nested guest VM inside it using the Realms feature. We do it for virt and sbsa-ref platforms. Signed-off-by: Pierrick Bouvier <[email protected]> ----- v2: - move test to its own file - add sbsa test - check output of `cca-workload-attestation report`
