ADD: PartialTrieView reconstruction from ExecutionWitness

[thomas-quadratic]

PR description

New feature for proof verification. This will include several steps:

1. Deserialising geth execution witness format into intermediary representation.
2. Building a View of the Partial Verkle Trie from that intermediary representation.
3. Gather Verification Queries
4. Call IPAMultiPointLib to verify the queries against the proof.

Fixed Issue(s)

Step 1 will probably be a PR in Besu.
Step 2 is this initial draft PR
Step 3 is coming
Step 4 will probably be a PR in rust-verkle.
