x86/sme: Replace occurrences of sme_active() with cc_platform_has()
Replace uses of sme_active() with the more generic cc_platform_has() using CC_ATTR_HOST_MEM_ENCRYPT. If future support is added for other memory encryption technologies, the use of CC_ATTR_HOST_MEM_ENCRYPT can be updated, as required. This also replaces two usages of sev_active() that are really geared towards detecting if SME is active.
