71f016c6eb42e1ac2c905e04ba4d20c2009e533f Remove old serialization primitives (Pieter Wuille)

ef17c03e074b6c3f185afa4eff572ba687c2a171 Convert wallet to new serialization (Pieter Wuille)
65c589e45e8b8914698a0fd25cd5aafdda30869c Convert Qt to new serialization (Pieter Wuille)

Pull request description:

  This is the final step 🥳 of the serialization improvements extracted from #10785.

  It converts the LimitedString wrapper to a new-style formatter, and updates the wallet and Qt code to use the new serialization framework. Finally all remaining old primitives are removed.
