[Synapse] - Add support for workspace package

[idear1203]

Description

When developing custom applications or models, your team may develop various code artifacts like wheel or jar files to package your code.

In Synapse, workspace packages can be custom or private wheel or jar files. You can upload these packages to your workspace and later assign them to a specific Spark pool. Once assigned, these workspace packages are automatically installed on all Spark pool sessions.

More details can be found here: https://docs.microsoft.com/en-us/azure/synapse-analytics/spark/apache-spark-azure-portal-add-libraries#workspace-packages
