I think we need to fully remove text_autosizing_window_size_override_ with this
patch

It's used in a few (not many) tests, e.g.
https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/fast/text...
,
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/web/tests/Text...
– should those tests go away too?

Oohh, that's right. I forgot how those tests work. We do want to keep those
tests. LGTM to land as-is.
