[ANegm-ETAS]

📌 Description

Process Improvement to add safety relevance and root cause to FMEA and DFA analysis elements
the new fields are added as optional and should have minimal impact.

• added to plat_saf_dfa, feat_saf_dfa, comp_saf_dfa:
  safety_relevant

• added to feat_saf_fmea, comp_saf_fmea:
  safety_relevant
  root_cause

This change is part of a larger change to update the safety analysis process

• Updating the fault models representation here : Anegm/fault models needs elements process_description#657
• Updating FMEA template to an xml model here: Anegm/per fmea json score#2789
