js--font-lock-keywords-2: Remove the 'for each' matcher

Browse Source 
* lisp/progmodes/js.el (js--font-lock-keywords-2):
Remove the 'for each' matcher.  First, because it was slow
(bug#56682), and second: the 'for each' syntax was only present in
Mozilla's dialect of JavaScript (added in version 1.5), and has
been deprecated for a decade now.
