Pull request description:

  ### Description

  WIP towards removing `rand` fixes #871

  The `rand` dependency was imported explicitly, but `rand` is also implicitly used through the `rand-std` feature flag on `bitcoin`.

  ### Notes to he reviewers

  **Updated:**

  `rand` was used primarily in two parts of `bdk`. Particularly in signing and in building a transaction.

  Signing:
  - Used implicitly in [`sign_schnorr`](https://docs.rs/bitcoin/latest/bitcoin/key/struct.Secp256k1.html#method.sign_schnorr), but nowhere else within `signer`.

  Transaction ordering:
  - Used to shuffle the inputs and outputs of a transaction, the default
  - Used in the single random draw __as a fallback__ to branch and bound during coin selection. Branch and bound is the default coin selection option.

  See conversation for proposed solutions.
