[llvm] [Offload] Explicitly create directories that contain tablegen output (PR #142817)

[Callum Fare via llvm-commits]

https://github.com/callumfare created https://github.com/llvm/llvm-project/pull/142817

This isn't required when building with Ninja, but with the Makefile generator these directories don't get implicitly created.
