move the default text breaking algorithm impl from HarfBuzz to Qt

there are several reasons to do this:
* text breaking is not a shaper's job;
* since the text breaking rules are bound to a specific Unicode version,
  updating Qt's internal unicode data would require updating the data in HB as well;
* makes porting to HurfBuzz-NG some easier
