Model copy does not accept project as an argument

[racinmat]

Copying model does not let you specify the model project, takes it from gcloud config.

#### Root cause
https://github.com/googleapis/python-aiplatform/blob/v1.70.0/google/cloud/aiplatform/models.py#L6667-L6673 does not accept the project, and although the model contains the correct project, it pulls the project from global initializer here: https://github.com/googleapis/python-aiplatform/blob/v1.70.0/google/cloud/aiplatform/models.py#L6725-L6727 
and this causes the problem and requires people to switch the project in `gcloud`.

Can you work around this using aiplatform.init(project='<project b>')?
