DiffuseGI and RayTracing samples are unavailable on certain hardware configuration

[LB-ArturZieba]

Describe the bug
Samples > Features > DiffuseGI and Samples > RHI > RayTracing samples are greyed out on a machine with AMD Ryzen 5 3600X 6-Core CPU and AMD Radeon RX 5700 XT GPU, but not on another machine with Intel Core i7-11700F CPU and NVIDIA GeForce RTX 3070 GPU. This seems like both of these are unavailable due to GPU not supporting RTX, but I could not find any explicit information that such hardware is required.

This issue also occurs on Windows and on the development (ec385c7) branch.

This issue should be treated as Minor priority.

Steps to reproduce

1. Launch AtomSampleViewer.Gamelauncher.
2. Check both Samples > Features > DiffuseGI and Samples > RHI > RayTracing samples.

Expected behavior
Samples can be opened.

Actual behavior
Samples are greyed out.
