Experimental support for Kitty image protocol in preview window
Close #3228

* Works inside and outside of tmux
* There is a problem where fzf unnecessarily displays the scroll offset
  indicator at the topbright of the screen when the image just fits the
  preview window. This is because `kitty icat` generates an extra line
  after the image area.

    # A 5-row images; an extra row at the end confuses fzf

* Example:

  fzf --preview='
    if file --mime-type {} | grep -qF 'image/'; then
      # --transfer-mode=memory is the fastest option but if you want fzf to be able
      # to redraw the image on terminal resize or on 'change-preview-window',
      # you need to use --transfer-mode=stream.
      kitty icat --clear --transfer-mode=memory --stdin=no --place=${FZF_PREVIEW_COLUMNS}x${FZF_PREVIEW_LINES}@0x0 {}
    else
      bat --color=always {}
