[LayoutNG] Rebaseline fast/writing-mode/border-image-vertical-lr.html

fast/writing-mode/border-image-vertical-lr.html produces
different results because, in legacy, block direction borders
applied to inline boxes affect positioning of the line box in
vertical-lr writing-mode, when they should not.

This patch rebaselines it, and also adds a minimized test to
check such borders do not affect line box positioning.

Gecko, and WebKit fail the test. Edge passes this test,
though it paints the border at the incorrect position.
Testing the border positoin is not ref-testable and that it
is not included.
