[PATCH] D116467: Deprecate `LLVM_LIBRARY_DIRS`

[John Ericson via Phabricator via llvm-commits]

Ericson2314 requested review of this revision.
Herald added projects: LLDB, LLVM.
Herald added subscribers: llvm-commits, lldb-commits.

In all cases we now just set a single lib dir, so the somewhat newer
`LLVM_LIBRARY_DIR` variable is more appropriate.

I still defined `LLVM_LIBRARY_DIRS` for sake of downstream projects, but
added a comment saying it was deprecated and should be removed. Is that
correct?

Also, I rearranged the definitions so they were more consistent.
