Pull request description:

  ### Description

  There is a bug in `bdk_bitcoind_rpc` where some new mempool transactions will not be emitted at all.

  This problem exists because the avoid-re-emission logic depends on rounded-to-nearest-second timestamps.

  The fix is to just emit all mempool transactions but wrap them in `Arc`s so that emission becomes cheap.

  **Background:** I tried using `bdk_bitcoind_rpc` as the chain-source to write an example to showcase the [`IntentTracker`](https://github.com/bitcoindevkit/bdk_wallet/pull/257). However, `bdk_bitcoind_rpc` failed to emit some mempool transactions.

  ### Notes to the reviewers

  The test added in c22c68f fails without these fixes.

  Some tests are removed as they are no longer relevant.

  ### Changelog notice

  ```md
  Fixed:
  - Some mempool transactions not being emitted at all. The fix is to replace the avoid-re-emission-logic with one which emits all mempool transactions.
  ```
