Breaking changes

• List of breaking changes introduced by our compatibility with WebGPU
  • ReadPixels and ProceduralTexture.getContent are now async
  • Shader support differences
• Use both mesh.visibility and material.alpha values to compute the global alpha value used by the soft transparent shadow rendering code. Formerly was only using mesh.visibility (Popov72)
• Depth renderer: don't render mesh if infiniteDistance = true or if material.disableDepthWrite = true (Popov72)
• Mesh.createInstance no longer make a unique Geometry for the Mesh so updating one Geometry can affect more meshes than before. Use Mesh.makeUniqueGeometry for old behaviour. (breakin)
• Ammo.js needs to be initialized before creating the plugin with await Ammo(); since Ammo introduced an async init in their library. (sebavan)
