Remove redundant clusterfuzz test

The test was added at r150718.  https://src.chromium.org/viewvc/blink?revision=150718

Currently It doesn't cause a crash even if we revert the change. It means the test is useless to keep stability.
Additionally the test looks less sophisticated and it is hard to get what it does.

Remove unnecessary [NoInterfaceObject] from testing IDL files

Testing IDL files no longer need [NoInterfaceObject],
as we now don't feed them into the list of main interface files
('main_interface_idl_files' in generated_bindings.gyp);
previously it was necessary because we didn't distinguish these files.

This removes the extended attribute, simplifying them.

Fix an MQ parsing related crash

When MediaQueryParser used valuesList.clear(), clear() cleared the list's values, but not the offset of the current read value.
This fixes that.

Explicitly mark first 2 args of addEventListener/removeEventListener as optional

addEventListener and removeEventListener should require 2 arguments
(per spec), but legacy content calls these with 0 or 1 arguments.

For background, see this bug:
https://code.google.com/p/chromium/issues/detail?id=249598

This results in a special case in the CG, and an IDL that doesn't reflect
reality.

This updates the IDL to reflect reality, and removes the special-casing
from the CG, removing 3 FIXMEs!

There's now only 1 EventTarget FIXME in the templates, namely
the frame security check (on window).

This changes
addEventListener.length
removeEventListener.length
...from 2 to 0, reflecting reality.
