On some platforms we used bUseLiveCodeEdit, which was expected to be present in the per-platform configuration block. At the same time, on Windows we rely on bSupportEditAndContinue from BuildConfiguration.
Modified the console platforms to use BuildConfiguration.bSupportEditAndContinue for consistency. However, there is some value in being able to control this setting per-platform, so I've left the existing properties and just renamed them bUseLiveCodeEdit -> bSupportEditAndContinue.
As a result, all platforms that support Edit and Continue are affected by BuildConfiguration.bSupportEditAndContinue. However, if XXPlatform.bSupportEditAndContinue is presetnt, it overrides the global.
Removed ClangToolChainOptions.EnableLiveCodeEditing and related code as it turns out it wasn't really used.

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.

- Implemented priority control on Unix platform
- Refactored RunnableThreadUnix implementation
- Bump resource limits for process scheduling priority (nice) if possible

This change does a few things:
* Improves compile times because the gen.cpp is inlined so less header parsing is required.
* Allows us to forward declare more types in the headers where we were not able to because the gen.cpp files did not have all the required headers included. The gen.cpp files required the header that generated it to include all the types because of the constructor and desructor in the gen.cpp need to know the full type.
