[CMake] Export utility targets to the build/install tree depending on LLVM_BUILD...

Summary:
Allow external projects to import test-related targets like FileCheck, count, not etc. and query binary paths, properties, etc.
This would be useful for LLDB, because it reduces the difference between in-tree vs. standalone builds and simplifies CMake logic.
