With introduction of FEAT_STATE_CHECK_ASYMMETRIC, the asymmetry of cores can be handled. FEAT_TCR2 is one of the features which can be asymmetric across cores and the respective support is added here. Adding a function to handle this asymmetry by re-visting the feature presence on running core. There are two possible cases: - If the primary core has the feature and secondary does not have it then the feature is disabled. - If the primary does not have the feature and secondary has it then, the feature need to be enabled in secondary cores.
