[DLCov] Move DebugLoc coverage macro to llvm-config.h (llvm#137787)

This patch follows the reversion of llvm#107279, which caused errors by
including `llvm/Config/config.h` in a public header. In order to reapply
that patch, this PR moves the definition of the config option to the
`llvm-config.h` header instead, so that it can be used publicly. This
patch also adds `LLVM_` as a prefix to the define, since it is now in a
public header.
