Dennis Kobert 45b04f4eb9 Lay groundwork for directly rendering to the canvas without a cpu roundrip (#1291)
* Add Texture handle type

* Add Texture View to shader inputs

* Implement basic rendering pipeline

* Render first texture using render pipeline

* Fix output color space

* Precompute the rendering pipeline

* Move gpu context creation to editor api

* Port gpu-executor nodes to node registry

* Fix canvas nodes and make code compile for non wasm targets

* Pin wasm-bindgen version

* Disable miri temoporarily for better ci times

* Fix formatting

* Remove unsafe block

* Bump wasm-pack version

* Bump wasm-bindgen version

* Add gpu feature guard for push node

* Make Into node async
