[out-of-flow] Resolved right and bottom are wrong inside a vertical inline
containing block
https://bugs.webkit.org/show_bug.cgi?id=324063
<rdar://problem/187295559>
Reviewed by Antti Koivisto.
The resolved value of an auto right or bottom subtracts offsetLeft, offsetWidth
and marginRight, all physical, from the containing block's padding box, so it
needs that box's physical width or height.
RenderInline::innerPaddingBoxWidth and innerPaddingBoxHeight are logical, which
matches only in a horizontal writing mode; in vertical-rl a span 20px wide and
40px tall reported right as 40px instead of 20px.
