Add command line switch to enable region based columns.
This needs to be a separate switch - we cannot lump it together with
--enable-experimental-webkit-features , because we don't want
to unconditionally enable region based columns when running LayoutTests
(there are LayoutTests that compare rendering in the old and new multicol
implementations, using internals.settings.setRegionBasedColumnsEnabled(true)).
