[bazel] Update llvm-config.h and disable DebugLoc tracking

In c588224, @chapuni set
LLVM_ENABLE_DEBUGLOC_COVERAGE_TRACKING to 1, but from what I can tell,
this is not the default setting for CMake builds. I think the intention
was mostly just to update llvm-config.h to fix the Bazel build.

I'm adding LLVM_ENABLE_DEBUGLOC_ORIGIN_TRACKING as well to fix the build
for the same purpose.
