[css-text] New value 'break-spaces' for the white-space property

Finally the CSS WG decided [1] to move back the 'break-spaces' value to
the 'white-space' property. This makes the parsing logic easier than
the previous approach of using the 'overflow-wrap' property.

This new value prevents the white-space sequence to collapse and gives
breaking opportunities after every preserved white-space.

Additionally, unlike 'pre-wrap', non-collapsible spaces or tabs at the
end of a line cannot be hung or visually collapsed, since we want them
to be preserved and broken.
