Now that we build lines incrementally, we no longer need the atomic line
splitting API.
The new InlineLevelIterator and LineBuilder setup does have some
regressions from the old behavior, but we can deal with them as we go.
In the past, the base class implementation of this was used to descend
into subtrees and paint children. That is now taken care of by
StackingContext::paint_descendants() instead, and nothing used this.
This more clearly expresses the purpose of this flag. Since only
CSS::WhiteSpace::Nowrap sets this value to false and it does not respect
linebreaks, this made the most sense as a flag name.
This commit refactors the text chunking algorithm used in
TextNode::ChunkIterator. The m_start_of_chunk member parameter has been
replaced with a local variable that's anchored to the current iterator
at the start of every next() call, and the algorithm is made a little
more clear by explicitly separating what can and cannot peek into the
next character during iteration.
The code handling the rendering of the text-decoration-line got moved
into its own function to reduce clutter.
The CSS property text-decoration-line now supports underline, overline
and line-through.
Creating a ChunkIterator allows you to iterate over the text in a
Layout::TextNode at your leisure by calling next() when you want
another chunk.
This is one of many steps towards improving inline layout.

A label's format is: <label>Label text</label>
So, a TextNode is created as a child of the Label node, and EventHandler
will send events to the TextNode. This changes TextNode to accept mouse
events if its parent is a Label, and to forward those events upward.
The generic is<T>() uses dynamic_cast which is fine in the majority
of cases, but when one of them shows up in profiles, we can make it
faster by answering the is-a question manually.
