Merge bitcoin/bitcoin#22787: refactor: actual immutable pointing

Browse Source 
54011e7aa2 refactor: use CWallet const shared pointers when possible (Karl-Johan Alm)
96461989a2 refactor: const shared_ptrs (Karl-Johan Alm)

Pull request description:

  ```C++
  const std::shared_ptr<CWallet> wallet = x;
  ```
  means we can not do `wallet = y`, but we can totally do `wallet->DestructiveOperation()`, contrary to what that line looks like.

  This PR

  * introduces a new convention: always use const shared pointers to `CWallet`s (even when we mutate the pointed-to thing)
  * uses `const shared_ptr<const CWallet>` everywhere where wallets are not modified

  In the future, this should preferably apply to all shared pointers, not limited to just `CWallet`s.

  Both of these serve the same purpose: to dispell the misconception that `const shared_ptr<X>` immutates `X`. It doesn't, and it's dangerous to leave this misconception as is, for obvious reasons.
