BGE: Add GL synchronization on ImageRender.refresh() without buffer.

Calling ImageRender.refresh() without passing a buffer object will
now perform the render (if not already started earlier with
ImageRender.render()) and wait for the render to complete.
This is done internally with a GLSync object to synchronize with the GPU.
This is only useful when doing offscreen render on texture target:
when refresh() returns, you are guaranteed that the texture is ready for use.

fbo = bge.render.offScreenCreate(width,height,samples,bge.render.RAS_OFS_RENDER_TEXTURE)
tex = fbo.color
ir = bge.texture.ImageRender(scene,camera,fbo)
ir.refresh()
--> tex is now ready for use
