Throw TypeError when addEventListener or removeEventListener are called without enough arguments

** Changes web-facing behavior **

This removes legacy behavior, per request of Tab:
it fixes some current compatibility problems which *are* causing pain,
but potentially breaks some old content.

Current behavior (not throwing a TypeError) was for compatibility in 2012,
though unspecified cause:
WebKit bug specifically special-casing this in JavaScriptCore bindings is:
[JSC] Regression: addEventListener() and removeEventListener() raise an exception on missing args
https://bugs.webkit.org/show_bug.cgi?id=85928

WebKit/Safari also has legacy behavior (matches current Blink/Chrome):
"For compatibility with legacy content, the EventListener calls are generated without GenerateArgumentsCountCheck."
http://trac.webkit.org/browser/trunk/Source/WebCore/bindings/scripts/CodeGeneratorJS.pm#L2823

However, IE and Firefox *do* throw (correctly), and this discrepancy is causing
compatibility problems:
removeEventListener with only one passed parameter...

Thus this CL aligns with spec, updating tests and removing legacy tests.
