[llvm] [cmake] Add possibility to use ChooseMSVCCRT.cmake when include LLVM library

Modify LLVMConfig to produce LLVM_USE_CRT variables in build-directory. It helps to set the same compiler debug options like in builded library.

Excuse me, I have add to reviewers people, who review this file. Add relative people, if needed, please.
This change helps to build library and user-tool with same flags.

Ping?

lgtm, it's in the LLVM_ namespace, so it couldn't hurt to record it.

[igorban]

Thanks!

Did this land?

[rnk]

I don't think so. Is there a committer interested in doing this? I'm busy.

[igorban]

I hope it will help to land. I was think, what "accepted"-action is enough for push changes.
