Manual merge of CL 4940744 because robomerge had issues.
Original Description:
Merging //Fortnite/Dev-Kairos to Main (//Fortnite/Main)
Getting ready for Install Bundle Manager merge to main. These are Engine/Core fixes

Fix FBuildPatchInstaller::Initialize() failing for manifests that did not include the empty tag.

Add Android Macros to disable optimization
Fix Android directory iteration for OBBs. FindFilesRecursive() now works.

Android file - When mounting an OBB, fix possibly mounting directories as files.

Fix Android directory iteration not returning the visitor result. This would cause IPlatformFile::FindFilesRecursively() to prematurely end iteration.

Fix GetVarArgs format specifier off by 1 error. These would only show up if you had the format specifier at the end of the format string and only with 'l' and not 'll'. In that case the code would walk off the end of the format string, usually into another static string.
Fix GetVarArgs to never walk off the end of the format string.

Fix FShaderCodeEntry ref counts being off by one.
This bug was exposed because [Project Name Redacted] doesn't load shaderlibs or the PSO cache until well after engine init. That means some FShaderResource's are loaded before shader libs or PSO cache and FShaderCodeLibrary::RequestShaderCode() can fail in FShaderResource::SerializeShaderCode().

- This can be overriden per platform in the [ShaderCompiler] section of the platform's Engine.ini by adding "r.Shaders.KeepDebugInfo"
- Also add in support for exporting the debug info on platforms where it can be stripped and stored as separate files ("r.Shaders.ExportDebugInfo") and this is also per platform.
- Add "r.Shaders.ExportDebugInfoMode" to control how the exported files are stored, 0 for loose or 1 for an uncompressed archive.
