To be able to setup GuC submission functions during engine init we need to commit to using GuC as soon as possible. Currently, the only thing that can stop us from using the microcontrollers once we've fetched the blobs is a fundamental error (e.g. OOM); given that if we hit such an error we can't really fall-back to anything, we can "officialize" the FW fetching completion as the moment at which we're committing to using GuC. To better differentiate this case, the uses_guc check, which indicates that GuC is supported and was selected in modparam, is renamed to wants_guc and a new uses_guc is introduced to represent the case were we're committed to using the GuC. Note that uses_guc does still not imply that the blob is actually loaded on the HW (is_running is the check for that). Also, since we need to have attempted the fetch for the result of uses_guc to be meaningful, we need to make sure we've moved away from INTEL_UC_FIRMWARE_SELECTED. All the GuC changes have been mirrored on the HuC for coherency.
