When linking shared libs (DSOs) under Linux, we need the -shared-libsan option. This will cause us to load the libclang_rt.asan-x86_64.so, etc and not static link so we need to add the path to the executable rpath.
https://github.com/google/sanitizers/issues/1086https://www.gitmemory.com/issue/google/sanitizers/1086/509784249
Add linux sanitizer information to build details if set. Should look something like this:
------- Build details --------
Using system toolchain.
Using clang (/usr/bin/clang++) version '8.0.1' (string), 8 (major), 0 (minor), 1 (patch)
Using bundled libc++ standard C++ library.
Using lld linker
Using llvm-ar : /usr/bin/llvm-ar
Building with: AddressSanitizer
Using fast way to relink circularly dependent libraries (no FixDeps).

We now only check for and use the system compiler if "-ForceUseSystemCompiler" command line is passed
Also don't default to epic compiler if -ForceUseSystemCompiler specified and we can't find the system compiler

- This allows for Confidential platforms to exist outside of the engine, and insert themselves in as needed
- Directory structure is, where .... mirrors the directory structure for Engine and projects
- /Platforms/XXX/....
- Moving to more data driven approach for ShaderPlatforms and PlatformInfo, where they can be read from DataDrivenPlatformInfo.ini files that live in the platform config folders
- Removed platform mentions from UBT, by way of changing some enums to partial classes with static members (see UnrealTargetPlatform)
- Various other UBT/UAT modifications to allow for looking in other locations for files
- THIS IS NOT A COMPLETE AND FINAL SOLUTION. WE WILL CONTINUE WORK IN DEV-BUILD BEFORE ITS READY FOR PRIMETIME
