[libc++abi] Fix ASAN build with older compiler-rt versions.
Summary:
compiler-rt recently added the `__asan_handle_no_return()` function that libc++abi needs to use, however older versions of compiler-rt don't provide this interface and that breaks the libc++abi build.
This patch attempts to fix the issues by using a macro to detect if `asan_interface.h` is new enough to provide the function.
