[WebSocket] Setting wrong value to binaryType should not raise exception
https://bugs.webkit.org/show_bug.cgi?id=97999

Reviewed by Yuta Kitamura.

Source/WebCore:

Don't raise exception when binaryType is the wrong value.
Instead, show an error message to console.

No new tests. Updated existing test.

* Modules/websockets/WebSocket.cpp:
(WebCore::WebSocket::setBinaryType): See the description.
* Modules/websockets/WebSocket.h:
(WebSocket): Removed ExceptionCode argument of setBinaryType().
* Modules/websockets/WebSocket.idl:
Removed "setter raises(DOMException)" and "[TreatReturnedNullStringAs=Undefined]".
They are no longer needed.

LayoutTests:

Update binary-type.html.
