Drop support for wpc-terminal

As I mentioned in the previous commit, I now use vterm.el as my primary
terminal. I wrote most of this Elisp when I first started using Emacs. I
know longer need it.

-;;; terminal.el --- My cobbled together terminal -*- lexical-binding: t -*-
-;; Author: William Carroll <wpcarro@gmail.com>
-
-;;; Commentary:
-;; My attempts at creating a sane Emacs terminal.  Most of this work was created
-;; before I discovered and fully adopted EXWM.  Prior to this, the appeal of
-;; having terminals inside of Emacs was appealing.  So appealing in fact that I
-;; was willing to work with inferior alternatives to non-Emacs terminals
-;; (e.g. `ansi-term') instead of GUI alternatives like `alacritty` because the
-;; productivity gains of having a terminal inside of Emacs might outweigh the
-;; shortcomings of that particular terminal.
-;;
-;; All of this changed, however, after discovering EXWM, since I can embed X11
-;; GUI windows inside of Emacs.  Therefore, most of this module is maintained
-;; for historical purposes.
-;;
-;; Benefits of `ansi-term':
-;; - Color scheme remains consistent between Emacs and terminal.
-;; - Same applies to my fonts.
-;;
-;; Downsides of `ansi-term':
-;; - Paging feels sluggish with programs like `cat` and `less`.
-;; - KBDs don't provide 100% coverage of what I expect from a terminal since
-;;   they were created to cooperate with Emacs.
