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

[Stephen Tozer via llvm-commits]

https://github.com/SLTozer created https://github.com/llvm/llvm-project/pull/137787

This patch follows the reversion of #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.
