[LayoutNG] Improved legacy write-back for multicol.

This fixes crashers in layout tests.

A recent change, probably
https://chromium-review.googlesource.com/c/chromium/src/+/912551
triggered a bunch of crashers in fast/multicol/ , because it calls
LayoutFlowThread::PageRemainingLogicalHeightForOffset(), which DCHECKs
on IsPageLogicalHeightKnown(). So have NG mark logical height as known,
to avoid the DCHECK failure.

In addition to fixing those 91 new crashers (note that the test
expectation file hadn't been updated to expect crashers for those), this
also fixes some old crashers. Most of them go from Crash to Failure, but
a few even pass now.
