* Added option to generate assembly files while compiling cpp files.
* Supported only on MSVC compiler for now.
* The generated files have the .asm extension and are located in the same Intermediate folder as the corresponding .obj

- Added IntermediateDirectoryNoArch to UEBuildModule (we can use this in the future to put generated definitions headers, which can help reduce rebuilds going between multi- and single-arch)

Changed how single files are built. We don't want to invalidate makefile everytime we build single files since it destroys turnaround times. With this change a single file compile can take 2s (+ the actual compile time).
The new behavior injects a special action per module when creating the makefile. These actions can be used to on-the-fly create a proper compile action that follows the rules of the module that the specific file belongs to.. In a normal build these actions are ignored since the logic deciding which actions to build is backtraced from which binaries we want to create.
When a specific file compile is triggered, the logic deciding which files to build search up all these special actions and create a lookup based on which folders the special actions handle. It then try to find the special action that handles the specific file. The matching special action then creates a compile action that can handle that specific file and then queue up the action for execution. If no special action is found it falls back to try to use actions that have this specific file as input (ispc files for example)
Details:
* Removed lots of custom code for "specific files" handling
* Changed so pch (both private and shared) always use definition file. Added #pragma once and change so pch wrapper file include definition file. This made the adaptive path and specific file easy to implement (just disable pch in compile environment and it will just work)
* Added SingleFileAction for both VCToolChain and ClangToolChain. It now works to compile specific headers and cpp files. (It creates wrapper files on the fly to be able to compile all header files (compiling headers directly blow up if there are circular includes)
* Fixed so GenerateClangDatabase mode works with new changes
* Moved the logic that makes sure all (directly) depending cpp files are recompiled when .h are included in the singlefile option

- remove dependency on LaunchEngineLoop.cpp which also allows compilation against engine to succeed
- LowLevelTestsRunner no dependency on engine modules required: Launch, Core, Project
- EXPLICIT_TESTS_TARGET definition for self-contained tests: test modules and targets that derive from TestModuleRules/TestTargetRules respectively
- Cleanup Launch dependencies from existing explicit tests
- Cleanup redundant flags from existing explicit tests
- rename Self -> Foundation for in Horde
- additional platform fixes

This can be a lot of files if you request a very common header! For example -SingleFile=Runtime\Core\Public\Containers\Array.h currently would build over 22k UnrealEditor actions

* ActionGraphBuilder - Added AllowAsync parameter to CreateIntermediateTextFile which defaults to true.
* UEBuildModuleCPP - Added AllowAsync false to one place where the code touches the file after CreateIntermediateTextFile has been called
* UEBuildModuleCPP - Changed so code writing LiveCodingInfo.json is using same path as others when it comes to writing files

- 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)

Engine FExec (exec commands) changes
- Add Exec_Dev and Exec_Editor virtual functions to allow implementing Exec for specific configurations.
- Add a UBT flag: bAllowExecCommandsInShipping as a master switch to allow or remove Exec in shipping.
- The default Exec implementation calls both Exec_Dev and Exec_Editor, when they are available.
- Blueprint ExecuteConsoleCommand will now ask the console manager to process the command before falling back to Player and GEngine Exec. This is to make sure that if exec commands are disabled the blueprint node is still able to execute console commands.
