mesa: Handle uninitialized textures like other textures in get_tex_level_parameter_image

Instead of catching the special case early, handle it by constructing a
fake gl_texture_image that will cause the values required by the OpenGL
4.0 spec to be returned.

Previously, calling

    glGenTextures(1, &t);
    glBindTexture(GL_TEXTURE_2D, t);
    glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, 0xDEADBEEF, &value);

would not generate an error.

Anuj: Can you verify this does not regress proxy_textures_invalid_size?
