arch: enable HAS_LTO_CLANG with KASAN and KCOV

Both KASAN and KCOV had issues with LTO_CLANG if DEBUG_INFO is enabled. 
With LTO inlinable function calls are required to have debug info if they
are inlined into a function that has debug info.

Starting with LLVM 17 this will be fixed ([1],[2]) and enabling LTO with
KASAN/KCOV and DEBUG_INFO doesn't cause linker errors anymore.
