LibWeb: Improve support for white-space CSS property (#2348)

Add reasonable support for all values of white-space CSS property.

Values of the property are translated into a 3-tuple of rules:

    do_collapse:        whether whitespace is to be collapsed
    do_wrap_lines:      whether to wrap on word boundaries when
                        lines get too long
    do_wrap_breaks:     whether to wrap on linebreaks

The previously separate handling of per-line splitting and per-word
splitting have been unified. The Word structure is now a more
general Chunk, which represents different amounts of text depending
on splitting rules.
