[gn build] add build file for tsan runtime
Linux-only for now. Some mac bits stubbed out, but not tested. Good enough for the tiny_race.c example at https://clang.llvm.org/docs/ThreadSanitizer.html : $ out/gn/bin/clang -fsanitize=address -g -O1 tiny_race.c $ while true; do ./a.out || echo $? ; done While here, also make `-fsanitize=address` work for .c files. Differential Revision: https://reviews.llvm.org/D99795
