fwk: Update more intrusion switch info

- [x] SYSTEM_BBRAM_IDX_CHASSIS_WAS_OPEN
  - Implemented
- [ ] SYSTEM_BBRAM_IDX_CHASSIS_MAGIC (RTC Battery ever removed)
  Never set. Is this useful on lotus/azalea without RTC?
- [x] SYSTEM_BBRAM_IDX_CHASSIS_TOTAL
  - Implemented
- [x] SYSTEM_BBRAM_IDX_CHASSIS_VTR_OPEN (Opened while system off)
  - Implemented in this commit. Tested on lotus. Works.
