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().

[CL 4833753 by daniel lamb in Main branch]
Replaced expensive CRT to[w]lower() / to[w]upper() calls with locale-independent implementations.
The semantics match standard C locale that all UE platforms use - only ASCII characters are considered.
* Simplified TChar IsLinebreak()
* New TChar::ToLower() and ToUpper() implementation
* Replaced all Str[n]icmp() implementations with a unified implementation that all platforms use
* Moved implementation inside a cpp file to reduce code bloat
* Added unit tests
* Fixed sign extension bug in the replaced Str[n]icmp()
The bug would only manifest for 1 and 2 byte signed character types. Also MicrosoftPlatformString forwarded Str[n]icmp() to correct but non-standard CRT calls. AFAICT only narrow strings containing non-ASCII characters on non-MS platforms was affected. See TChar::ToUnsigned() for more details.
