[XRay] Clean up XRay build configuration Summary: This change spans both LLVM and compiler-rt, where we do the following: - Add XRay to the LLVMBuild system, to allow for distributing the XRay trace loading library along with the LLVM distributions. - Use `llvm-config` better in the compiler-rt XRay implementation, to depend on the potentially already-distributed LLVM XRay library. While this is tested with the standalone compiler-rt build, it does require that the LLVMXRay library (and LLVMSupport as well) are available during the build. In case the static libraries are available, the unit tests will build and work fine. We're still having issues with attempting to use a shared library version of the LLVMXRay library since the shared library might not be accessible from the standard shared library lookup paths. The larger change here is the inclusion of the LLVMXRay library in the distribution, which allows for building tools around the XRay traces and profiles that the XRay runtime already generates.

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
