- Creates the UnrealArchitectures class, which wraps a list of UnrealArch objects
- UnrealArch is a single architecture, expandable enum-like struct
- There is no more concept of "no/default architecture", there is always a valid active architecture when building
- Most uses of "string Architecture" are replaced with one of the two above, depending if multiple architectures are supported or not
- UnrealArch has some platform-extensions for platform-specific naming (like Linux adds in LinuxName that turns, for instance, Arm64 -> aarch64-unknown-linux-gnueabi, which is used in folder names, etc)
- UnrealArch has bIsX64 which can be used determine intel instruction set (as opposed to arm)
- TargetRules class has an "Architecture" accessor that will return a single architecture if the active architectures is a single architecture, or throw an exception if multiple. This is useful in a majority of the cases where a paltform can only have a single architecture active in TargetRules (microsoft platforms, for instance, will create separate targets when compiling multiple architectures at once)
- Added UnrealArchitectureConfig class, which contains all the architecture information for a platform (what architectures are supported, what ones are currently active for given project, etc)

* Updated RulesAssembly to add the parent assembles to the assembly cache so the types in the other assemblies can be used when calling the constructor.

This can be enabled by modifying `UnrealEngine\Engine\Saved\UnrealBuildTool\BuildConfiguration.xml` like so:
<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
<BuildConfiguration>
<bShaderCompilerWorkerTrace>true</bShaderCompilerWorkerTrace>
</BuildConfiguration>
</Configuration>
- Added a build configuration xml value, `bShaderCompilerWorkerTrace`.
- Turning this on will set USE_SHADER_COMPILER_WORKER_TRACE=1
- Move the parameter -nothreading to be set when we launch the process instead of internally as an extra cmd line arg.
- Unreal Insights uses a separate thread to send events so threading support is needed for the program. When we have USE_SHADER_COMPILER_WORKER_TRACE enabled we need to turn off `-nothreading`.
- When USE_SHADER_COMPILER_WORKER_TRACE is enabled we pass in `-trace=default` to get CPU event markers.
- The SCW program needs to turn on the following defines to be able to perform CPU and memory traces:
ENABLE_LOW_LEVEL_MEM_TRACKER=1
UE_MEMORY_TAGS_TRACE_ENABLED=1
UE_TRACE_ENABLED=1
- Instrument Shader Compiler Worker with TRACE_CPUPROFILER_EVENT_SCOPE. This are no-ops when this is turned off.
todo: Make the shader compiler worker inherit the trace args from the main process it was launched from.

- Drives the WITH_EDITOR preprocessor definition.
- Updated TargetRules.bBuildEditor to check the target type or bCompileAgainstEditor.
- Removed usages of TargetRules.bBuildEditor from UBT and replaced it with checks against the target type or the new bCompileAgainstEditor flag where necessary.

Per-project rules assembly csprojen.
Previously: all .build.cs and .target.cs were being grouped into a single project, which resulted in duplicate symbols when trying to build the project.
Now: multiple assemblies csprojs are generated, one for each Engine & Game project. Also, includes preprocessor defines.
