🛠 Summary of changes

PR to remove vectors of trust when our final partner migrates to acr_values

Note:
The EIPP implementation relies on vectors of trust. This does not seem to be the right approach, as when I talked to them about it months ago, it sounded like EIPP was not evaluated on a per-request level. However, it was never updated for a new implementation, and then development was cancelled.

I don't want to make any decisions regarding EIPP, and it sounds like it might be a feature that comes back. Therefore, I mostly just marked the related specs as pending so that the team can make decisions about how to update it when the time comes.

TODO:
rename files to remove Vot from namespacing

This is a Herculean task that is hard to review. Have you considered an approach that has more steps that can be progressively deployed?

@vrajmohan i have thought about it, but it's embedded in a lot of code, making it pretty tough to remove piecemeal. i also worry, based on shifting priorities and such, that leaving it to be piecemeal means that some parts of it are never removed or get forgotten about

happy to take suggestions about how you might approach it in a step-by-step fashion, though, if you have any! i won't have time before i go on vacation, but could reconsider when i get back

I am closing this in favor of #12718, #12721, #12741 and #12748
