docs(threat-model): make measured boot out of scope

Browse source 
Add an explicit note that measured boot is out of scope of the threat
model. For example, we have no threat related to the secure
management of measurements, nor do we list its security benefits
(e.g. in terms of repudiation).

This might be a future improvement to the threat model but for now
just acknowledge it is not considered.
