boot state: schedule static callbacks
Many of the boot state callbacks can be scheduled at compile time. Therefore, provide a way for a compilation unit to inform the boot state machine when its callbacks should be called. Each C module can export the callbacks and their scheduling requirements without changing the shared boot flow code.
