Pull request description:

  This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).

  ---

  Move `NodeImpl` from `interfaces/node.cpp` to `node/interfaces.cpp`
  Move `ChainImpl` from `interfaces/chain.cpp` to `node/interfaces.cpp`
  Move `WalletImpl` from `interfaces/wallet.cpp` to `wallet/interfaces.cpp`

  No changes to any classes (can review with `git diff --color-moved=dimmed_zebra`)

  Motivation for this change is to move node and wallet code to respective directories where it might fit in better than `src/interfaces/`, but also to remove all unnecessary code from `src/interfaces/` to unblock #19160 review, which has been hung up partially because of code organization. Building on top of this PR, #19160 should now be able to organize interface implementations more understandably in `src/node/` `src/wallet/` `src/ipc/` and `src/init/` directories instead of having so much functionality all in `src/interfaces/`
