Merge bitcoindevkit/bdk#1373: Wrap transactions as Arc<Transaction> in TxGraph
8ab58af093ff295b86c3f8189aa96dea313092c4 feat(chain)!: wrap `TxGraph` txs with `Arc` (志宇)

Pull request description:

  ### Description

  This PR makes `TxGraph` store transactions as `Arc<Transaction>`.

  `Arc<Transaction>` can be shared between the chain-source and receiving structures. This allows the chain-source to keep the already-fetched transactions (save bandwith) and have a shared pointer to the transaction (save memory).

  Our current logic to avoid re-fetching transactions is to refer back to the receiving structures. However, this means an additional round of locking our receiving structures.

  ### Notes to the reviewers

  This will make more sense once I update the esplora/electrum chain sources to make use of both #1369 and this PR. The result would be chain sources which would only require locking the receiving structures twice (once for initiating the update, and once for applying the update).

  ### Changelog notice

  * Changed `TxGraph` to store transactions as `Arc<Transaction>`. This allows chain-sources to cheaply keep a copy of already-fetched transactions.

BDK Esplora

BDK Esplora extends esplora-client to update bdk_chain structures from an Esplora server.

Usage

There are two versions of the extension trait (blocking and async).

For blocking-only:

bdk_esplora = { version = "0.3", features = ["blocking"] }

For async-only:

bdk_esplora = { version = "0.3", features = ["async"] }

For async-only (with https):

bdk_esplora = { version = "0.3", features = ["async-https"] }

To use the extension traits:

// for blocking
use bdk_esplora::EsploraExt;
// for async
// use bdk_esplora::EsploraAsyncExt;

For full examples, refer to example-crates/wallet_esplora_blocking and example-crates/wallet_esplora_async.
