Create integration tests for labeler, and update toy model.

[tcsnfkx]

In toy model,

• Add AttributesUpdater to set country_code.
• Use ConditionalAssignment instead of ConditionalMerge to extract demo
  from profiles.
• Make the profile type consistent when multiple profile types are set.
• Format the textproto.
  Create events to test the "cookied" branch of the toy model.

Consider adding something like SCOPED_TRACE(absl:StrCat("ApplyAndValidate(", model_path, ", ", input_path, ", ", output_path)); to the top of this function to get better error messages.

Nit: should we use 2022 now?

Why there is no demo? Was the demo redistribution matrix removed from the model?

It does not work.

Only label or quantum_labels of LabelerEvent are written to output (https://github.com/world-federation-of-advertisers/virtual-people-core-serving/blob/main/src/main/cc/wfa/virtual_people/core/model/population_node_impl.cc#L126). This model has demo model, but does not write the redistributed demo to label or quantum_labels. We can update the model in next PR if we want.
