Prevent Personalize ranking processor from being created as part of an ad hoc pipeline

[msfroh]

In opensearch-project/OpenSearch#8163, we made a change to pass the pipeline creation context to a processor factory, so the factory can take appropriate action depending on how it's being called.

For the Personalize ranking processor, we should fail if invoked as part of a search request (i.e. in an ad hoc pipeline), to make sure that we're not creating a new AWS Personalize client on every search request. This requires a check in the Personalize processor factory.

We will create the new release candidate 2.9.0.1 for this fix.
