Support Emacs 28's emojis about circe

[wasamasa]

This feature is part of a yet to be released Emacs version, so no. Circe supports Emacs 24.4 and above.

Would it be worth to reopen this now that Emacs 28.1 has been released?

Note this can be achieved by doing this:

;; Use "C-x 8 RET <type name>"
(defun --set-emoji-font (frame)
  "Adjust the font settings of FRAME so Emacs can display emoji properly."
  (set-fontset-font t 'symbol (font-spec :family "Noto Color Emoji") frame)
  (set-fontset-font t 'symbol (font-spec :family "Segoe UI Emoji") frame 'append)
  (set-fontset-font t 'symbol (font-spec :family "Symbola") frame 'append))
;; For when Emacs is started in GUI mode:
(--set-emoji-font nil)
;; Hook for when a frame is created with emacsclient
;; see https://www.gnu.org/software/emacs/manual/html_node/elisp/Creating-Frames.html
(add-hook 'after-make-frame-functions '--set-emoji-font)

Enabling Unicode icons in emoji mode also helps (emojify-display-style -> unicode).

I've looked at smiley.el again and all it does is replacing smileys like :-) with a small image or emoji. That's different from what I've expected (turning emoji glyphs into pretty pictures) and unrelated to the other suggestion (using a supported emoji color font to automatically turn all emoji glyphs into pretty pictures).

In Emacs 28.1, Noto Color Emoji and Symbola are already used, so unless you're on a Win32 system (which might only have Segoe UI), the above customization should not be needed.
