Remove XEmacs support from cperl-mode

* lisp/progmodes/cperl-mode.el (condition-case)
(cperl-electric-parens-mark, cperl-del-back-ch)
(cperl-do-not-fontify, cperl-mode, cperl-find-pods-heres)
(cperl-write-tags, cperl-tags-hier-init, cperl-perldoc)
(cperl-build-manpage): Remove XEmacs support.

There's a lot of support code in here for older versions of Emacs that
could be removed, too.
