- Splitting symbol generation and shader "debug info" generation into two different cvars. This should now allow us to generate symbols post-packaging without generating different shader variants. This should also enable us to always generate symbols and still have the final deduplicated shader sizes.
- r.Shaders.Symbols is now the primary way to enable shader symbols for debugging.
- r.Shaders.GenerateSymbols can be enabled to always generate symbols without writing them to disk.
- r.Shaders.WriteSymbols can be used to force write symbols if they were previously generated.
- r.Shaders.ExtraData can be used to generate shader names for engine runtime systems to use.
- NotifyShaderCooked replaced with NotifyShaderCompiled, prep for upcoming non-cook symbol writing.
- PC DXC shader compiles should only generate debug info when requested, not all the time.
- PC FXC shader compiles should generate debug info when requested, not just when r.Shaders.Optimize is 0.

Adding shader symbol export path override cvar. This cvar supports specifying the shader platform name via "{Platform}".
Adding Luke's change for having build machine specific shader configs.

- 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
