Jason Simmons aeb54d46dc libtxt: handle newlines during invocation of the minikin line breaker (flutter/engine#4237) ...

minikin::LineBreaker does not convert newline characters into line breaks
in its output.  Previously libtxt's version of LineBreaker container a patch
that added a large width offset for a newline in order to force wrapping to
the next line.  This works if the offset exceeds the paragraph's width
constraint.  But if the paragraph is laid out with infinite width, then the
text after the newline will continue on the current output line.

This change separates the paragraph's text into newline delimited blocks and
feeds each block separately to the minikin LineBreaker.

Also, libtxt was breaking the input styled text runs at newline boundaries.
This is no longer necessary.
