change(state): Refactor the structure of finalizable blocks (#7035)
* Add and use `FinalizableBlock`

This commit adds `FinalizableBlock`, and uses it instead of
`ContextuallyVerifiedBlockWithTrees` in `commit_finalized_direct()`

* Use `ContextuallyVerifiedBlockWithTrees`

This commit passes `ContextuallyVerifiedBlockWithTrees` instead of
passing separate `finalized`, `history_tree` and `note_commitment_trees`
when storing blocks in the finalized state.

* Apply suggestions from code review

* add docs to new methods

* fix existing doc

* rename `ContextuallyVerifiedBlockWithTrees` to `SemanticallyVerifiedBlockWithTrees`

* Refactor docs

* Refactor comments

* Add missing docs, fix typo

* Fix rustfmt

change(state): Refactor the structure of verified blocks (#7025)
* Refactor `CheckpointVerifiedBlock`

This commit turns `CheckpointVerifiedBlock` into a wrapper of
`SemanticallyVerifiedBlock` since both structs have the same fields.

* Refactor `ContextuallyVerifiedBlockWithTrees`

This commit uses `SemanticallyVerifiedBlock` in
`ContextuallyVerifiedBlockWithTrees` instead of
`CheckpointVerifiedBlock`.

feat(state): Send treestate from non-finalized state to finalized state (#4721)
* Add history trees for each height in non-fin state

* Refactor formatting

* Pass the treestate to the finalized state

I created a new structure `FinalizedBlockWithTrees` that wraps the
treestate and the finalized block. I did that because the original
`FinalizedBlock` is `Eq`, but `HistoryTree` can't be `Eq`.

This makes Zebra faster because:

1. The finalized state doesn't retrieve the treestate from the disk if
the non-finalized state supplies it.

2.The finalized state doesn't recompute the treestate if the
non-finalized state supplies it.

* Check block commitment before updating hist tree

* Store Sprout commitment trees in non-fin state

* Send trees for the root block to fin-state

When committing a block and sending the treestate from the non-finalized
state to the finalized state, Zebra was sending trees that correspond to
the tip block instead of trees that correspond to the root block of the
best chain. This commit fixes that.

* Refactor doc comments

* Refactor block finalization

2. feat(db): Add address balance indexes to the finalized state (#3963)
* Add an empty balance_by_transparent_addr column family

* Add an AddressBalanceLocation type for balance_by_transparent_addr

* Add serialization for balance_by_transparent_addr types

* Add round-trip tests for the new serialized types

* Add missing round-trip and serialized equality tests

* Add a network field to DiskWriteBatch

* Refactor confusing all_utxos_spent_by_block argument

It was actually just the UTXOs from the state spent by the block,
excluding the UTXOs created and spent within the block.

But now we need it to contain all the spent outputs,
including the ones created by the block.

* Read and update address balances in the finalized state

* Update raw data snapshots for transparent address balances

* Add test-only deserialization for transparent addresses

* Add high-level snapshot test code for address balances

* Add high-level snapshots for address balances

* Increment the state version after NU5 testnet 2 rollback

1. feat(db): Store transactions in a separate database index, to improve query speed (#3934)
* Implement disk serialization for block headers and transactions

* Re-order column family initialization to match the design

* Add new empty transaction column families

* Split writing block header and transaction data

* Re-order column families for consistency

* Update write snapshots for transaction split

* Use split block and transaction data when reading

* Update snapshots to include genesis transaction hash location

* Filter all prefix iterators to make sure they return the correct values

* Test that the new transaction indexes are consistent

* Add some cleanup TODOs

* Increment the database format to version 15

* Remove unused fisk format impls for Block

* Add a missing prefix extractor for transaction locations

* Make the database generic over the thread mode

* Replace prefix iteration with iteration from a key, and a filter

Prefix iteration caused database hangs.

* Manually iterate through transaction locations to re-create blocks

Also:
- re-write disk read API to avoid iterator hangs
- move disk read API to ReadDisk
- re-write impl rocksdb::AsColumnFamilyRef to a where clause, for consistency

* Update the database version so it's larger than the NU5 testnet 2 version
