Fix robust resource initialization with clipped CopyTexSubImage2D. When CopyTexSubImage2D calls were clipped against the bounds of the read framebuffer by the underlying renderer backends, the robust resource initialization code assumed that the original destination area would be overwritten by the renderer, which was not the case. Add new tests which were previously failing on macOS with the ES2_OpenGL and ES3_OpenGL backends. The Metal backend is still failing and a follow-on bug has been filed.
