Implement clipping masks, stroke align, and stroke paint order (#2644)

Browse Source 
* refactor: opacity + blend_mode -> blend_style

* Add code for clipping

* Add alt-click masking

* Clip to all colors. Fill option

* Fix undo not working. Fix strokes not being white

* Allow clipped to be grouped or raster

* Switch to alpha mode in mask-type

* add plumbing to know if clipped in frontend and add fill slider

* Attempt at document upgrade code

* Fix fill slider

* Add clipped styling and Alt-click layer border

* Use mask attr judiciously by using clip when possible

* Fix breaking documents and upgrade code

* Fix fixes

* No-op toggle if last child of parent and don't show clip UI if last element

* Fix mouse styles by plumbing clippable to frontend

* Fix Clip detection by disallowed groups as clipPath according to SVG spec doesn't allow <g>

* Add opacity to clippers can_use_clip check

* Fix issue with clipping not working nicely with strokes by using masks

* Add vello code

* cleanup

* Add stroke alignment hacks to SVG renderer

* svg: Fix mask bounds in vector data

* vello: Implement mask hacks to support stroke alignment

* Move around alignment and doc upgrade code

* rename Line X -> X

* An attempt at fixing names not updating

* svg: add stroke order with svg

* vello: add stroke order with by calling one before the other explicitly

* fix merge

* fix svg renderer messing up transform det

* Code review; reorder and rename parameters (TODO: fix tools)

* Fixes to previous

* Formatting

* fix bug 3

* some moving around (not fixed)
