Replace Rustybuzz with Parley for text layout, and add text tilt parameter (#2739)

* replace rustybuzz with parley for text layout handling

change text input direction based on text direction

* Code review

* change default character spacing to 0

* add shear to text node

this also adds migration code for documents that don't have shear

* shear migration for text node

- add shear property
- set character spacing to 0

* use old max_width and max_height in text migration if available

* Final code review pass

* Add units to the parameters
