`RHI/RayTracing` sample does not work on either Vulkan/dx12, Windows/Linux

[martinwinter-huawei]

Describe the bug
Testing both o3de and atom-sampleviewer on their latest development branches, the RHI/RayTracing sample does not work and also crashes sometimes.
The output is either the grey background or sometimes flashing images of the correct output and sometimes it crashes in Vulkan::Queue::SubmitCommandBuffers() after the final GetContext().QueueSubmit().

This appears to be different from the issue #621.

Steps to reproduce
Steps to reproduce the behavior:

1. Checkout the most recent version of o3de and the o3de-atom-sampleviewer
2. Try to run Samples/RHI/RayTracing on Windows/Linux with either -rhi=vulkan/dx12

Expected behavior
There is visual output.

Actual behavior
Grey background and recurring freezes.

Found in Branch
development

On that note, manually tried to start all samples on Linux and found the following issues:

• Samples
  • Checkerboard (crash)
  • LightCulling (short flicker and then only gray background)
• Performance
  • 100KDrawable_SingleView (gray and no imgui interface anymore)
  • 100KDraw_10KDrawable_MultiView (same)
• RHI
  • RayTracing (grey and/or crash)
• RPI
  • SceneReloadSoakTest (1 image, then gray)

Tested on Windows as well, the same samples do not work (except for RPI/SceneReloadSoakTest) as on Linux.
