Merge bitcoin/bitcoin#30094: rpc: move UniValue in blockToJSON

b77bad309e rpc: move UniValue in blockToJSON (willcl-ark)

Pull request description:

  Fixes: #24542
  Fixes: #30052

  Without explicitly declaring the move, these `UniValues` get copied, causing increased memory usage. Fix this by explicitly moving the `UniValue` objects.

  Used by `rest_block` and `getblock` RPC.
