[Epoch Sync] EpochSyncProof validation (#12020)
2c40e53 
Issue: #11932

Implements EpochSyncProof validation, according to:
- [design
doc](https://docs.google.com/document/d/14Itc9Hs7ewTRmcGANid9UCaYcJzaLzzM7FsvYYIFKDY/edit#heading=h.p2oiicluwd6o)
-
[`epoch_sync.rs`](https://github.com/near/nearcore/blob/d6d6e4782f7d57a7b7acc2894e1668355012ff74/core/primitives/src/epoch_sync.rs)

Summary:
- Move block merkle proof retrieval logic from `Chain` to a separate
trait (`MerkleProofAccess`). Make `Store` implements this trait so that
we can `get_block_proof` while serving `EpochSyncRequest` from a
separate thread and having no access to `Chain`.
- Refactor `verify_approval` and `compute_bp_hash` so that we can use it
for proof validation.
- Derive `first_block_info_in_epoch` from block header.
- Implement the validation logic.
- Add 2 more fields to the proof
  - `EpochSyncProofPastEpochData::protocol_version`
- `merkle_proof_for_first_block` generated at height of final block of
current epoch.
- Apparently, we need to add even more to enable generating
`merkle_proof_for_first_block` at the bootstrapped node. That will be
done as a follow-up issue:
#12255.
- Create a bunch of follow-up issues (added to the [tracking
issue](near/near-one-project-tracking#73)):
  - #12255
  - #12256
  - #12258
  - #12259
  - #12260
