- Refactored SDK versioning into more formalized APIs for all platforms. Currently UBT will not error with bad versions, but that is coming.
- Turnkey updated to use new BuildUtilities

- Removed the function to return a single TP, and wrapped the functionality in a simple single required function (platform just has to add TPs to an array, high level code manages init and cleanup of the array)
- Stripped unncessary code from all TPs
- Collapsed the desktop targetplatform modules into 1 per platform
- Renamed LinuxAArch64NoEditorTargetPlatfortm to LinuxAArch64TargetPlatform to match the other non-editor platforms
- Deleted AllDesktopPlatform

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
