Fix
webgl/2.0.y/conformance/textures/misc/tex-image-with-format-and-type.html
webgl/1.0.x/conformance/textures/misc/tex-image-with-format-and-type.html
For now, resolve the texture upload data (NativeImage) premultiplication
status at the call site. Later on, this will be exposed correctly
through NativeImage.
* LayoutTests/fast/canvas/webgl/tex-image-with-format-and-type.html: Removed.
Old variant of the test that now exists in the CTS.
