Related issue: Closes #28519

Rendering using outputStruct() to multiple render targets doesn't handle depth with WGSL because @Builtin('frag_depth') not included in the output struct definition. (GLSL unaffected).

Include builtins as required and simplify, avoiding the var in main fragment shader function and aligning with standard code with the output named 'output'.

I just tested the changes locally in my app. That works, with this changes the depthNode works in conjunction with the outputNode like with the colorNode.
Then my ticket #28519 can also be closed as solved.
