- 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)

RHI header dependency cleanup
- Reducing other header dependencies from RHIDefinitions.h
- Moved a few functions to the new RHIStrings.h
- Uniform buffer layout initializer moved to its own file to reduce RHI dependency on MemoryLayout.

* Fixed new iwyu code to be compatible with changes coming from ue5 main (CompileCppFiles is now protected and UEBuildModuleCPP.cs calls CompileAllCPPFiles instead of CompileCppFiles directly)

[CL 23631280 by henrik karlsson in ue5-main branch]
* Added IWYU toolchain which can be enabled with -IWYU
* Added IWYU mode that can be used with -Mode=IWYU. This can be used to modify code files
* Binary of include-what-you-use that contains a ton of fixes to make ue build

* Added code to fixup definitions provided through .build.cs files. There are actually strict rules around the syntax of defines (reading msvc documentation). There should be no space before or after the '=' character. so "MY_DEFINE = 1" is actually invalid. When building with header units this actually produce invalid data but in normal builds it seems to swallow it (even though the documentation says it shouldn't)
I would have wanted to fix the code producing bad definition format but it is in a whole bunch of modules so I suspect external teams might have this too, so instead we fix it up by trimming the strings before and after '='

- Mac changes to compile separately, but link together (with lipo) after making two .dylibs/executables
- Removed FixDylibDependencies on Mac by making "stub dylibs" to mimic what Windows does with import libs, to solve circular dependencies
- Added DependenciesToSkipByArchitecture to ModuleRules that is used, when making a new single-arch LinkEnvironment from a multi-arch LinkEnvironment, to strip out libraries, etc, that should not be included with that single architecture
