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

- valid settings for r.DumpShaderDebugInfo are now 0-3
- 0 - don't dump (unchanged)
- 1 - always dump (unchanged)
- 2 - dump on error (ie compilation failure)
- 3 - dump on generated errors or warnings
- implementation details:
- mode 2 and 3 are achieved by reissuing shader compilation jobs
- jobs are issued as normal with no DumpInfoPath set so the platform specific shader compilers will not dump additional files
- jobs that fail to compile (mode 2) or generate any errors/warnings (mode 3) are reissued with a valid DumpInfoPath which will cause the platform specific shader compilers to dump the additional files
- the directory creation is deferred until the second pass on mode 2 or 3 as well so no empty directories are created
- limitations:
- shader compilation jobs which crash the shader compile worker will not produce debug dump info on modes 2 or 3 as we will not get an opportunity to reissue the jobs

- FileCache can dynamically allocate/release memory as needed
- Preloaded lines are locked in the cache. One the preloaded memory has been read, the line is unlocked. This prevents preloaded lines from being evicted before they're needed.
- Cache line size changed from 64k to 16k, reduce fragmentation due to locked preloaded lines
