Add BiConsumer support in AssociationLinker

[nakamura-to]

This pull request introduces support for the BiConsumer functional interface in the AssociationLinker, alongside the existing BiFunction support. This enhancement expands the flexibility of AssociationLinker to handle operations requiring BiConsumer types. No additional features or breaking changes are introduced.

This pull request makes it possible to write an interface annotated with AggregateStrategy as follows:

@AggregateStrategy(root = Emp.class, tableAlias = "e")
interface EmpStrategy {
  @AssociationLinker(propertyPath = "dept", tableAlias = "d")
  BiConsumer<Emp, Dept> dept = (e, d) -> {
    e.dept = d;
    d.employees.add(e);
  };

  @AssociationLinker(propertyPath = "address", tableAlias = "a")
  BiConsumer<Emp, Address> address = (e, a) -> {
    e.address = a;
  };
}

Before this pull request, it was necessary to write it like this:

@AggregateStrategy(root = Emp.class, tableAlias = "e")
interface EmpStrategy {
  @AssociationLinker(propertyPath = "dept", tableAlias = "d")
  BiFunction<Emp, Dept, Emp> dept = (e, d) -> {
    e.dept = d;
    d.employees.add(e);
    return e;
  };

  @AssociationLinker(propertyPath = "address", tableAlias = "a")
  BiFunction<Emp, Address, Emp> address = (e, a) -> {
    e.address = a;
    return e;
  };
}
