Avoid kStrokeAndFill_Style in BorderShadowLayerDelegate::OnPaintLayer

Avoid kStrokeAndFill_Style in BorderShadowLayerDelegate::OnPaintLayer

We're looking at deprecating kStrokeAndFill_Style in Skia, so this CL's
main focus is removing the use of the flag.

While in this area, I've also updated the impl to draw the shadow using
Canvas::DrawRoundRect instead of going through a path.

I presume the stroke bit of the shadow is not intentional/significant, because
we're not setting a stroke width.  If it is, we could always outset the rrect by
0.5 or something.
