fix(shader): normalize view direction in Universal pipeline

[marko1olo]

Replaced direct assignment of input.viewDirectionWS to output.WorldSpaceViewDirection with normalize(input.viewDirectionWS) in OceanFramework_Generated.shader. This addresses the TODO comment indicating it wasn't normalized by default in the universal pipeline, ensuring consistent behavior across rendering pipelines.
