Summary: Adds a CMake check for whether the compiler used to build the XRay library supports XRay-instrumentation. If the compiler we're using does support the `-fxray-instrument` flag (i.e. recently-built Clang), we define the XRAY_NEVER_INSTRUMENT macro that then makes sure that the XRay runtime functions never get XRay-instrumented. This prevents potential weirdness involved with building the XRay library with a Clang that supports XRay-instrumentation, and is attempting to XRay-instrument the build of compiler-rt.
