[WebGL][EFL][GTK][Qt]Add support for OES_vertex_array_object.

https://bugs.webkit.org/show_bug.cgi?id=109382

Patch by Kondapally Kalyan <kalyan.kondapally@intel.com> on 2013-02-13
Reviewed by Kenneth Russell.

Source/WebCore:

Covered by fast/canvas/webgl/oes-vertex-array-object.html

This patch adds support for using Vertex Array Object with OpenGl.
The patch adds support for loading necessary opengl functions
and support for checking GL_ARB_vertex_array_object. The support
for OES_vertex_array_object is advertised if GL_ARB_vertex_array_object is
supported.

* platform/graphics/OpenGLShims.cpp:
(WebCore::initializeOpenGLShims):
* platform/graphics/OpenGLShims.h:
(_OpenGLFunctionTable):
Added support for loading the necessary functions.

* platform/graphics/opengl/Extensions3DOpenGL.cpp:
(WebCore::Extensions3DOpenGL::createVertexArrayOES):
(WebCore::Extensions3DOpenGL::deleteVertexArrayOES):
(WebCore::Extensions3DOpenGL::isVertexArrayOES):
(WebCore::Extensions3DOpenGL::bindVertexArrayOES):
(WebCore::Extensions3DOpenGL::supportsExtension):

(WebCore):
(WebCore::Extensions3DOpenGL::isVertexArrayObjectSupported):
* platform/graphics/opengl/Extensions3DOpenGL.h:
(Extensions3DOpenGL):

LayoutTests:

Enable oes-vertex-array-object for EFL port.
