Replace Rustybuzz with Parley for text layout handling

[BKSalman]

related to #1105

this adds Parley which handles a lot of text related stuff for us

I made this PR to get feedback on the changes

and after this is accepted, some of the listed TODOs from this issue can be resolved easily, which I could either add to this PR, or make another PR for them

I've created this simple file that I tested with, you can also use it (you need to use a font that supports Arabic, something like Tajawal)

it should look like this

TODOs:

• [x] Add parley
• [x] Remove rustybuzz
• [ ] Migrate text node from old implementation
  • [ ] Change default character spacing to 0
  • [ ] detect the number of parameters that exist on the text node and do the migration only when it doesn't match the new number of parameters
• [x] Add shear
