Percentage heights can be resolved against any parent if writing mode is orthogonal.

It doesn't matter then if the height of the containing block is auto, since
we're going to resolve the percentage height against a *width* anyway. Check
for containing block writing mode orthogonality earlier. It used to be omitted
for render flow threads (we'd just skip unconditionally), and we want to be
able to resolve against the column width.

This makes fast/multicol/fixed-column-percent-logical-height-orthogonal-writing-mode.html
pass in the new multicol implementation.
