WGSLNodeBuilder: Sampler for compute shader (#30033)

* Update WGSLNodeBuilder.js

Arrays are not currently taken into account by the wgslTypeLib. However, with the struct extension #29908, arrays will also become important as a type.

* enables the use of samplers in compute shaders

Since textureSampleLevel is usable in compute shaders, this small PR allows sampler to be used in compute shaders for this purpose

* Update WGSLNodeBuilder.js
