Asset Processor errors: specific Shader Asset jobs

[LB-KacperKapusta]

Describe the bug This issue was created based on the comment in #12588. The following Shader Asset jobs complete processing with errors:

/o3de/Gems/AtomTressFX/Assets/Shaders/HairRenderingFillPPLL.shader platform: linux /o3de/Gems/Atom/Feature/Common/Assets/ShaderLib/Atom/Features/RayTracing/RayTracingSrgs.shader platform: pc, android, server, linux /o3de/Gems/Terrain/Assets/Shaders/Terrain/Terrain_DepthPass.shader platform: linux /o3de/Gems/Terrain/Assets/Shaders/Terrain/Terrain_Shadowmap.shader platform: linux /o3de/Gems/Terrain/Assets/Shaders/Terrain/TerrainMacroClipmapGenerationPass.shader platform: linux /o3de/Gems/Terrain/Assets/Shaders/Terrain/TerrainDetailClipmapGenerationPass.shader platform: linux /o3de/Gems/Terrain/Assets/Shaders/Terrain/TerrainPBR_ForwardPass.shader platform: linux

The error messages for the mentioned jobs are:

• Invalid buffer count -1
• ShaderBuilderUtility: Failed to parse output layout
• ShaderBuilderUtility: Could not create the output contract for the fragment function PPLLFillPS
• Can't open include file

Please note that Linux affected assets have to be verified on Linux OS.

Steps to reproduce

1. Create a new project in Project Manager built in Source engine configuration (https://www.o3de.org/docs/welcome-guide/setup/setup-from-github/building-windows/).
2. Build the project.
3. Run the Asset Processor and wait for the scan to finish.

Expected behavior All assets are processed without errors.

Actual behavior The Shader Asset jobs complete processing with errors.
