This commit implements conditional compilation for ASan helper code. As convey to me by @EricWF, string benchmarks with UBSan have been experiencing significant performance hit after the commit with ASan string annotations. This is likely due to the fact that no-op ASan code is not optimized out with UBSan. To address this issue, this commit conditionalizes the inclusion of ASan helper function bodies using `#ifdef` directives. This approach allows us to selectively include only the ASan code when it's actually required, thereby enhancing optimizations and improving performance. While issue was noticed in string benchmarks, I expect same overhead (just less noticeable) in other containers, therefore `std::vector` and `std::deque` have same changes. To see impact of that change run `string.libcxx.out` with UBSan and `--benchmark_filter=BM_StringAssign` or `--benchmark_filter=BM_StringConstruct`.
