clipboard: Add support for several more clipboards

Browse source 
This implements essentially the same heuristic as neovim, with the additional
(existing) special support for Cygwin.
See: e682d799fa/runtime/autoload/provider/clipboard.vim (L55-L121)
  - pbcopy, pbpaste (macOS)
  - cygwin (Windows running Cygwin)
  - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set)
  - xclip (if $DISPLAY is set)
  - xsel (if $DISPLAY is set)
  - lemonade (for SSH) https://github.com/pocke/lemonade
  - doitclient (for SSH) http://www.chiark.greenend.org.uk/~sgtatham/doit/

# This file has support for doing system clipboard copy and paste operations
# from the command line in a generic cross-platform fashion.
#
# On OS X and Windows, the main system clipboard or "pasteboard" is used. On other
# Unix-like OSes, this considers the X Windows CLIPBOARD selection to be the
# "system clipboard", and the X Windows `xclip` command must be installed.
# This is uses essentially the same heuristic as neovim, with the additional
# special support for Cygwin.
