Add support for the MCC update response version 8. Versions 5-6 are already covered by the existing flags conversion, and 7 isn't used. The capabilities field in iwl_mcc_update_resp is 32 bits wide now, and the flags moved, so some more changes are needed. While at it, convert the flags to bool (to avoid having to deal with BIT(16) specially etc.) and use the struct_size() macro for the memory allocation.
