Add support for callable references to BeanRegistrarDsl

BeanDefinitionDsl is allowing to create a bean from a callable
reference with its parameters autowired by type,
BeanRegistrarDsl should allow that too. For example:

class SampleBeanRegistrar : BeanRegistrarDsl({
    registerBean<MyRepository>()
    registerBean(::myRouter)
})

fun myRouter(myRepository: MyRepository) = router {
    ...
}
