Final cleanup of layout tests with FormControlsRefresh enabled

The [1] CL enabled the FormControlsRefresh feature by default for
Windows, Linux, and ChromeOS, which changed many layout tests. This
is the final patch cleaning up after the rebaseline effort.

One test just needed a modification (button-with-float), while the
other four are test issues. I've created bugs for each and marked
them in TestExpectations.
