pvmfw: Refactor get_or_generate_instance_salt

This is a rather complicated method that looks up instance.img, get the
salt if present, generates it if not. Additionally, it matches dice
measurement with recorded information from first boot. It also records
all this information in instance.img. It additionally has logic to skip
the checks for rkpvm.

Refactor this to get_recorded_entry / dice_measurements_matching /
record_instance_entry.

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
