This is required because subsequent shader compilation steps assume that the code has been fully preprocessed. In particular, the dead code elimination system does not handle macros such as ones in BindlessResources.ush.

* Track namespaces for symbols
* Re-emit namespace scopes
* Conservatively include symbols from all namespaces in minified code (as if they were all global)
* Additional parsing work will be required to more accurately track used symbols based on active namespaces (i.e. handle `using` keyword, etc.)
* Added RemoveDeadCode() overload that takes an explicit list of required symbols instead of just an entry point name

Declarations like `struct { uint Param; } Foo;` were previously incorrectly removed from code.
Also report explicit error when encountering 'namespace' keyword (which is currently unsupported)

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.

- each platform compilation request is now wrapped in __try/__except rather than a single exception handling block at the top level of the worker; this allows us to log an exception (with callstack) as a compilation error and continue the batch
- remove SEH code from ShaderConductorContext, the above makes this redundant (and it didn't provide any actionable information)
- strip down SEH code in D3DShaderCompiler; now only used for the purposes of pre-compiling with DXC in the case of an FXC crash. dumping preprocessed source will be handled in a different manner in a forthcoming CL
- minor change in the DXC precompile path to not log an unnecessary warning when performing an explicitly-requested DXC precompile

- Making ConstantBufferType a constructor only argument. This removes the duplicated logic of calling ShouldUseStableConstantBuffer.
- Moving ShouldUseStableConstantBuffer to ShaderCompilerCommon.
- Made UE::ShaderCompilerCommon::ParseParameterType array arguments const
