WebGPURenderer: Fix Hardware Clipping issues

[RenaudRohlinger]

Related issue: #28237

Description

Clipping in the WebGPURenderer is not working when using vertexNode as setupHardwareClipping is defined in setupPosition. This PR fixes the issue by moving it to setup.
Also this feature highlighted the fact that compileAsync was missing the group argument resulting in an error.
