Do not use LayoutProgress for a UA shadow element of a PROGRESS element.

Do not use LayoutProgress for a UA shadow element of a PROGRESS element.

The old behavior was the first child element of PROGRESS UA ShadowRoot used
LayoutProgress if the PROGRESS has -webkit-appearance:none.  However,
LayoutProgress does nothing if its associated element has no appearance.  So
the behavior made no sense.

This CL has no behavior changes.
