Merge bitcoin/bitcoin#28583: refactor: [tidy] modernize-use-emplace

fa05a726c2 tidy: modernize-use-emplace (MarcoFalke)

Pull request description:

  Constructing a temporary unnamed object only to copy or move it into a container seems both verbose in code and a strict performance penalty.

  Fix both issues via the `modernize-use-emplace` tidy check.
