acpi/ghes: prepare to change the way HEST offsets are calculated
Add a new ags flag to change the way HEST offsets are calculated. Currently, offsets needed to store ACPI HEST offsets and read ack are calculated based on a previous knowledge from the logic which creates the HEST table. Such logic is not generic, not allowing to easily add more HEST entries nor replicates what OSPM does. As the next patches will be adding a more generic logic, add a new use_hest_addr, set to false, in preparation for such changes.
