Merge bitcoindevkit/bdk#1582: refactor!: Implement generics for `CheckPoint`, `LocalChain`, and `spk_client` types

93a382df07a4d2ccafc13164d0b98abd2ae03119 refactor!: make `CheckPoint`, `LocalChain`, and `SpkClient` take a generic (Wei Chen)

Pull request description:

  Implements bitcoindevkit/bdk#1937.

  ### Description

  This PR is a step towards header checkpointing for `bdk_electrum`. The goal is to be able to store whole headers in `CheckPoint` so they do not have to be re-downloaded. Storing headers this way would be a prerequisite for caching of merkle proofs and for median time passed.

  ### Notes to the reviewers

  ### Changelog notice

  * `CheckPoint` takes in a generic.
  * `LocalChain` and `ChangeSet` take in generics.
  * `spk_client` types can take in generics.
