This PR introduces an optional property that provides a mechanism to disable the "all zero/one` data validity check when loading flash seeds as part of keymgr advancement.
The motivation is to support wider usage with unprovisioned flash information pages, which will not have these pages initialized and thus will fail keymgr advancement due to the current lack of flash scrambling.
