Change RenderStyle::getRoundedInnerBorderFor to take ints for border widths
https://bugs.webkit.org/show_bug.cgi?id=107331

Reviewed by Levi Weintraub.

Borders are always represented as ints yet RenderStyle::
getRoundedInnerBorderFor upcasts from int to LayoutUnit when
calling getRoundedInnerBorderFor.

No new tests, no change in functionality.
