[llvm] [orc-rt] Simplify CallableTraitsHelper specialization inheritance NFC. (PR #206869)

[Lang Hames via llvm-commits]

https://github.com/lhames created https://github.com/llvm/llvm-project/pull/206869

Make CallableTraitsHelper specializations inherit directly from ImplT. This is a no-op, but will simplify upcoming patches that will capture more information about the callable type.
