arch/x86: Refactor CAR_GLOBAL quirk for FSP1.0
These platforms return to romstage from FSP only after already having torn CAR down. A copy of the entire CAR region is available and discoverable via HOB. Previously, CBMEM console detected on-the-fly that CAR migration had happened and relocated cbmem_console_p accoringlin with car_sync_var(). However, if the CAR_GLOBAL pointing to another object inside CAR is a relative offset instead, we have a more generic solution that can be used with timestamps code as well.
