Add support of conditional decorators

[z4kn4fein]

Currently, the container picks every decorator with the same service type during resolution. It would be great to add more control over the decorator selection like:

class A : IService { }
class B : IService { }
class ADecorator : IService {}
class ServiceDecorator : IService {}

container
    .Register<IService, A>("A")
    .Register<IService, B>("B")
    .RegisterDecorator<IService, ServiceDecorator>()
    .RegisterDecorator<IService, ADecorator>(config => config.When(typeInfo => typeInfo.Type == typeof(A)));

container.Resolve<IService>("A"); // new ADecorator(new ServiceDecorator(new A()));
container.Resolve<IService>("B"); // new ServiceDecorator(new B());
