Add default values to MACHINE_FEATURES using the new filter_default_features() function. This change obsoletes the variables MACHINE_FEATURES_BACKFILL and MACHINE_FEATURES_BACKFILL_CONSIDERED. Instead, all defaults are added via MACHINE_FEATURES_DEFAULTS and users can opt out of any of these using MACHINE_FEATURES_OPTED_OUT. Hopefully the variable naming here is easier for people to understand and remember. Migration notes: - MACHINE_FEATURES will now get the default features added automatically. You will need to review these and add any features you do not want to use to MACHINE_FEATURES_OPTED_OUT. - If you previously set MACHINE_FEATURES_BACKFILL_CONSIDERED, use the new variable MACHINE_FEATURES_OPTED_OUT instead. - If you previously modified MACHINE_FEATURES_BACKFILL, don't do that.
