Merge bitcoindevkit/bdk#471: moving the function wallet_name_from_descriptor from...

2fc81141806ace8f12e5a019c0866f16fa8a02dc moving the function wallet_name_from_descriptor from blockchain/rpc.rs to wallet/mod.rs as it can be useful not only for rpc (Richard Ulrich)

Pull request description:

  ### Description

  Moving the function wallet_name_from_descriptor from rpc.rs to mod.rs
  Since the local cache for compact filters should be separate per wallet, this function can be useful not only for rpc.

  ### Notes to the reviewers

  I thought about renaming it, but waited for opinions on that.
