Speed up byte-compilation and autoload generation by avoiding mode-hooks

This prevents emacs-lisp-mode-hook from being run everytime an
autoload file is generated, which can account for a fraction of
package installation time depending on the hooks the user has
configured.

* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Use delay-mode-hooks.

* lisp/emacs-lisp/autoload.el (autoload-find-file)
(autoload-find-generated-file): Use delay-mode-hooks.
