[LOCK Spec] Opens from initial 0.8 commit

[bluegate010]

• "A vendor-unique key-retrieval algorithm can easily be leveraged into a METD-generation algorithm"
  • Not quite sure what this line item means.
• "Acknowledgements"
  • Do we need a separate section at the end for this?
• "Revision" and "Version" headers.
  • Do we need both?
• "Caliptra Core firmware can detect which ratchet secrets are all-zeroes, randomized, or all-ones. This can be done by representing a counter in fuses, which maps to ratchet secret states."
  • Need to decide whether this (and all the explanatory text) belongs in the spec.
