[ion] 24414: - Remove SMSS's code for signaling the "init" event. - Make ExpInitNls responsible for NLS initialization in Phase 0 as well, to clean up the code in ExpInitailizeExecutive a bit. - Initialize the system time/clock in Phase 1, not in Phase 0. - Do HAL Phase1 initialization as the first step in Phase 1 initialization, then initialize the system clock (since the HAL's RTC is now configured). - Do Ob Phase 1 init in Phase 1 initialization, not in phase 0. - Do Ke Phase 1 init after HAL

Log:
- Remove SMSS's code for signaling the "init" event.
- Make ExpInitNls responsible for NLS initialization in Phase 0 as well, to clean up the
code in ExpInitailizeExecutive a bit.
- Initialize the system time/clock in Phase 1, not in Phase 0.
- Do HAL Phase1 initialization as the first step in Phase 1 initialization, then
initialize the system clock (since the HAL's RTC is now configured).
- Do Ob Phase 1 init in Phase 1 initialization, not in phase 0.
- Do Ke Phase 1 init after HAL, Ob and Ex phase 1 inits.
- Initialize NLS for Phase 1 after Ke Phase 1, instead of much later.
