EEVEE Raytracing on Intel Arc wasn't working as there were no rays generated. The reason was that the raytract tile compact shader didn't set count the correct tiles it needed due to atomic operations that were initialized without atomic. This PR solves the issue by using atomic operations to initialize the counts. We also tried memory barriers but that didn't fix the problem. Other shaders were also tested if they have this issue, but they were setup in a specific shader or where done using a race condition (SSS) which is working.
