Update new BigQuery driver to only use project-id in qualified names if it differs from credentials (#18843)

* Update new BigQuery driver to only use project-id in qualified names if it differs from credentials

Add new key to db-details for :bigquery-cloud-sdk when a database is updated, called :project-id-from-credentials, and extract the project-id from the service account creds when the database is saved

Updating logic in bigquery-cloud-sdk QP to only include the project-id when qualifying an Identifier, if the project-id (override) value is set, and its value differs from the :project-id-from-credentials value mentioned above

Adding a test to confirm that a card query continues to work after changing the associated DB's driver from :bigquery to :bigquery-cloud-sdk

Change all syncs in the test to {:scan :schema} to speed them up (deeper level not needed)
