[Autofill] Make usage of structured name compatible with factory pattern

Prior to this change NameInfo had a member for the structured address
tree of type NameFull. This CL replaces this member with a
unique pointer to the base class AddressComponent.

By this, it becomes possible to make a finch-controlled replacement of
the structured name tree with a new, differently structured version
using a factory. This is necessary for a secure rollout of honorific
prefixes, that will introduce a new root node to the address tree that
will hold both the old NameFull and an additional honorific prefix.

This CL replaces the assignment and comparison operators with methods
that are implemented in the base class and work the same for all
derived address component classes. By this, the call becomes independent
on the type of the calling instance.

This CL also changes the concept how nodes are registered as child nodes
of a component. Before, the pointers to the child nodes have been
supplied on construction time. Now, the child registers itself to its
parent node. By this, the code gets simpler and less prone to errors.
