Merge bitcoin/bitcoin#22283: build: Replace $(AT) with .SILENT

8494dca Replace $(AT) with .SILENCE. (Dmitry Goncharov)

Pull request description:

  This reduces the amount of syntax noise in the makefiles.
  Setting V=1 still enables verbose logging.

  The only noticeable difference in behavior is that, unless V=1 is specified, make won't print its own messages like
  make: Nothing to be done for 'all', make: 'all' is up to date, or touch <file>, if -t is specified.
