bug#37079: 26.2.90 feature request; bury-frame command for desktop-wm

[VanL]

Hello,

The frame commands in

  info:emacs#Frame Commands

don't include a command to `bury-frame' as distinct from minimize-frame (C-z) 
in the desktop-wm.

Having 'bury-frame' allows quick switching away-from-then-return-back-to Emac's 
focus-frame while working with not-Emacs-app.  I hope this does not require 
very deep coding complications into the specific desktop-wm's frameworks making 
this feature request not worth the effort.  Thank you.
