refactor(startup): implement registration of core init functions
Similar to how the secondary init functions were already registered
via ESP_SYSTEM_INIT_FN, do the same for the core init functions.
This MR doesn't actually move the init functions into respective
components yet. This has to be carefully done in follow-up MRs.
