- add new IShaderFormat API for separate preprocessing and compilation; backends can implement one or the other depending on the return value of SupportsIndependentPreprocessing
- add support for executing preprocessing in the cook process prior to job submission and constructing job input hashes based on preprocessed source (and a subset of the environment used as compile inputs). controlled by a cvar for now and disabled by default
- add a BaseShaderFormat class in ShaderCompilerCommon which implements common behaviour for output of debug data - note this function is only called for formats which support independent preprocessing, so is expected to be used only by formats which have been converted to use this API
- add new cvars for output of some additional shader debug data - 1. a txt file containing the input hash a.k.a. job cache key 2. a text file containing all diagnostic messages (errors and warnings) for the job
- minor change to how input hashes are constructed for pipeline jobs - sum hashes as 256-bit ints instead of adding to a buffer and re-hashing. faster and simpler, and also more collision resistant (sum of two well distributed hashes equally well distributed)

MPCook and Shaders: Change ShaderSymbolExport to export to different .zip files when in a -MultiprocessId environment.
Add part of the implementation for merging the different zip files created by CookWorkers together. The rest of the implementation requires reading from .zip files and will be coming in a future change.

* Adding "inline" in front of const/constexpr variables in headers
* Adding includes
* A few moves of ctor/dtor to cpp file

Add new interface function AllowsDevelopmentObjects to ITargetPlatform
This function makes a clearer distinction for what assets will be considered development vs what assets should be considered EditorOnly
A platform should be allowed to cook editor only objects but not development. The inclusion of AllowsDevelopmentObjects creates that distinction

Moved GetTypeHash function to be hidden friend instead of put directly in global namespace.
Note that the function/operator needs to be fully inlined in the type or placed in the cpp. If the function is added as friend but then implemented outside the type then hidden friend optimization won't work.
This should improve compile time somewhat according to msvc devs.

- Saves ~0.3ms on PS4/XB1 (Dynres = 100%).
-Add possibility to disable grass velocity output when WPO velocity is enable (only effective when r.velocity.enablevertexdeformation != 0 and r.OptimizedWPO = true)

This has the effect of reducing the number of platforms that say they support RayTracing which directly reduces the number of shader platforms that "support" RayTracing.
