Herald added a project: LLVM.

Instead of duplicating functionality for building native versions of
tblgen and llvm-config, add a function to set up a native tool build.
This will also be used for llvm-nm in a follow-up.

This should be NFC for tblgen. For the native llvm-config, it's a
behavior change in that we'll use llvm_ExternalProject_BuildCmd instead
of constructing the build command manually, always build in Release, and
reference the correct binary path for multi-config generators. I believe
all of these changes to be bug fixes.
