Log Message:
-----------
[WebGPU] https://playground.babylonjs.com/#18WTCK doesn't render trees and
stones
https://bugs.webkit.org/show_bug.cgi?id=285186
rdar://142087137
Reviewed by Gerald Squelart.
Correctly preserve alpha values during copyExternalImageToTexture so
premultiplied
data doesn't get passed which is lossy.
