Integrate raw WGPU textures into Vello rendering pipeline (#1897)

* WIP

* Introduce `Raster` enum and plumb texture injection to vello

* Use correct texture formas for usage in vello

* Add missing cache implementations

* Update vello image override api

* Use git version of vello

* Fix type for upload texture node

* Improve crash resiliance

* Fix warnings

* Remove unused node impls
