.NET: [BREAKING] Enable sharing of workflow instances across concurrently executing runs (#1464)

Browse Source 
* refactor: remove unused internals

* feat: Execution Mode for sharing a workflow among concurrent runs

* feat: Update WorkflowHostAgent to support concurrent execution

* Also update AsAgent APIs to support injecting a CheckpointManager and an IWorkflowExecutionEnvironment

* fix: Make Read logic consistent in DeclarativeWorkflowContext
