Preload encoded-kb on MS-Windows

[Eli Zaretskii]

On MS-Windows, the startup code always causes encoded-kb to be loaded,
because of this snippet from mule-cmds.el

    ;; On Windows, override locale-coding-system,
    ;; keyboard-coding-system with system codepage.  Note:
    ;; selection-coding-system is already set in w32select.c.
    (when (boundp 'w32-ansi-code-page)
      (let ((code-page-coding (intern (format "cp%d" w32-ansi-code-page))))
        (when (coding-system-p code-page-coding)
          (setq locale-coding-system code-page-coding)
          (set-keyboard-coding-system code-page-coding)
          (set-terminal-coding-system code-page-coding))))

This calls set-keyboard-coding-system, which in turn loads encoded-kb
to enable Encoded Keyboard minor mode.

I think this means we should preload encoded-kb on Windows.  Does
anyone disagree?
