Switching the concurrency runtime to use the common SWIFT_STDLIB_TRACING to control whether the concurrency runtime enables tracing. The old process required passing bot the `SWIFT_STDLIB_TRACING` and `SWIFT_STDLIB_CONCURRENCY_TRACING` macro to the concurrency build or it would fail to build. It's not clear that there are any environments where it is desirable for swiftCore to have tracing enabled and not have swift_Concurrency tracing enabled or vice versa. Replacing the concurrency-specific macro with a single common macro. If it is desirable, we can teach the build system to avoid passing `SWIFT_STDLIB_TRACING` to a specific target if an option is not set. rdar://165777240
