Computed min-width/height for auto depends on box.

Resolved value of min-width and min-height for auto min sizing of flex
and grid items may be 'auto'. We based this on the computed style of the
shadow including parent. Instead we should rely on whether the element
will actually be a rendered flex/grid item.

Firefox Nightly passes all added tests.

The mentioned bug fixed is actually about using the shadow including
parent for finding parent computed style instead of the flat tree
parent, but that is no longer relevant as we look at the layout tree.
