[avb] Collect hash descriptors when verification succeeds

This cl uses `avb_descriptor_foreach()` to collect all the
hash descriptors once the verification succeeds and checks
that there's no unknown, duplicated or non-hash descriptor
in the vbmeta.

We will extract the partition digest from the collected
hash descriptors later.
