GraphQL Simple Data Provider DELETE_MANY and UPDATE_MANY Support

[maxschridde1494]

The goal here is to add an alternative to the virtual DELETE_MANY and UPDATE_MANY actions that trigger multiple DELETE and UPDATE requests under the hood. If the GraphQL Schema supports bulk deletes / updates, the Data Provider can be initialized with the bulkActionsEnabled option (turned off by default) and bulk DELETE_MANY and UPDATE_MANY will light up.
