-----------
column-count: 1 should create a multi-column container

Reviewed by Sam Weinig and Antti Koivisto.
Per spec, we need to create a multi-column container whenever either
column-count or column-width is not 'auto'. That includes column-count: 1;
https://www.w3.org/TR/css-multicol-1/#the-multi-column-model
* LayoutTests/TestExpectations:
Adjust test failures due to actually doing multicol layout for 1 column.
New failures:
- monolithic-overflow-*.tentative failures due to test errors
https://github.com/web-platform-tests/wpt/issues/55152
- multicol-span-all failures due to painting errors
https://bugs.webkit.org/show_bug.cgi?id=299854
- overflow-clip-010 due to some weird 'overflow: clip' bug
https://bugs.webkit.org/show_bug.cgi?id=299857
- resize-in-strict-containment-nested because we can't fragment multicol well
