  [ASTMatchers] Migrate away from ArrayRef(std::nullopt) (NFC) (#145840)

ArrayRef has a constructor that accepts std::nullopt.  This
constructor dates back to the days when we still had llvm::Optional.

Since the use of std::nullopt outside the context of std::optional is
kind of abuse and not intuitive to new comers, I would like to move
away from the constructor and eventually remove it.

This patch migrates away from std::nullopt in favor of ArrayRef<T>().
Note that {} would be ambiguous for perfect forwarding to work here.
