Merge bitcoin/bitcoin#25872: Fix issues when calling std::move(const&)

fa875349e22f2f0f9c2c98ee991372d08ff90318 Fix iwyu (MacroFake)
faad673716cfbad1e715f1bdf8ac00938a055aea Fix issues when calling std::move(const&) (MacroFake)

Pull request description:

  Passing a symbol to `std::move` that is marked `const` is a no-op, which can be fixed in two ways:

  * Remove the `const`, or
  * Remove the `std::move`

ACKs for top commit:
  ryanofsky:
    Code review ACK fa875349e22f2f0f9c2c98ee991372d08ff90318. Looks good. Good for univalue to support c++11 move optimizations
