[CL 12959964 by ben ingram in Main branch]
Fix issues causing material DDC values to be non-determinisic
- Shader code within resources sorted by hash
- Debug source code values sorted by type
Also add mechanism to serialize any MemoryLayout described type to string
- Makes it easier to inspect material data to find sources of non-determinism

- Shaders are searched by TypeName and PermutationId, so move those fields out of FShader and into separate arrays inside ShaderMap, to reduce cache misses while finding shaders

New CVars:
- r.RayTracing.CompileMaterialCHS (default 1)
- r.RayTracing.CompileMaterialAHS (default 1)
The value is read-only and must match between cook-time and run-time.

Rearranged DDC key composition since we need to flush out incorrectly keyed shaders in the cache.

known issues: RVT compression is not implementted, Android OpenGL will have R and G channels swapped for uncompressed streaming VT, no sRGB support

- Added shader pipeline hash as a key attribute.
- Added shaders from shader pipelines (they can have different code if RHI removes unused interpolators between the stages, like D3D does).

This was done because of MALI GPU limitation of 64kb texture buffer
- Changed default Precision of compute shaders to highp
- Added Texture Buffer GPU Support mobile
- Texture path controlled by GPUSceneUseTexture2D(requires recompile of shaders)
