  REGRESSION(271265 at main): Heap corruption crash while destructing WebGLMultiDraw
https://bugs.webkit.org/show_bug.cgi?id=265538

Unreviewed crash fix for Windows port.
Windows port was crashing after 271265 at main made WebGLExtension a
RefCounted subclass. Only WebGLMultiDraw has virtual destructor among
WebGLExtension subclasses. ~WebGLMultiDraw should be non-virtual as
well as other WebGLExtension subclasses.

* Source/WebCore/html/canvas/WebGLMultiDraw.h:
Removed virtual from ~WebGLMultiDraw.
