[llvm] [Support] Use an inherited constructor in DOTGraphTraits (NFC) (PR #164056)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/164056

This patch simplifies DOTGraphTraits with an inherited constructor.
This way, we do not need to repeat the constructor signature or
manually forward constructor arguments.
