vcl::Window::SupportsDoubleBuffering: respect VCL_DOUBLEBUFFERING_FORCE_ENABLE
Double buffering default is false, then can be enabled on a per-widget
basis, finally this can be overriden at runtime by the
VCL_DOUBLEBUFFERING_FORCE_ENABLE environment variable (so that
everything is painted using double buffering).
Let SupportsDoubleBuffering() also respect this variable, so code
calling SupportsDoubleBuffering() can react to the runtime override,
too.
