Target: print the message with formatting

[compnerd]

The message has a format specifier but was being printed unformatted.
This corrects the macro usage to use the formatting version. Improves
the debug logging only.

@swift-ci please test

Please also cherry-pick to swift/master-next, there is no automerger in this direction!

Stupid MSVC let this through, thanks clang!

Thanks for the heads up, will do. I wonder if it would be reasonable to have an automerger for this direction (CC: @shahmishal)

Unfortunately it's not quite as straight-forward, or we would have one already :-)

IIRC, it would have to be an auto-cherry-picker. @fredriss remembers all the details.

There was an automerger in this direction before the monorepo. But in the monorepo world, we cannot merge all the llvm and clang content from the stable branch into swift/master-next. I'm working on automation to point out the commits that are missing on master-next , but it's gonna take some time to become real.
