fix(lidar_centerpoint): add arg data_path, update model path

[lexavtanke]

Description

Belongs to Standardize a strategy for packages with downloaded artifacts
As autowarefoundation/autoware#3375 was merged to Autoware.universe. It is possible to use artifacts downloaded there.
#3141 was merged and the old path to the model file is outdated.

This PR introduces a new launch argument data_path in the form:
<arg name="data_path" default="$(env HOME)/autoware_data" description="packages data and artifacts directory path"/>
It also updates classifier_model_path and classifier_label_path args.

See #3137
