.NET: Add support for Subworkflows and many threading fixes (#1066)

* feat: Add support for Workflow-as-Executor

* Fixes routing of 'object' compile-typed variables to properly take in type information
* Fixes a concurrency issue in StepTracer

* fix: Make Subworkflow ExternalRequests work properly

* fix: Threading and Concurrency fixes; prep for OffThread Mode

* refactor: Remove dead code around OffStreamRunEventStream

Currently not used, and will be replaced with a rewrite when brought back, so having it in the change is not valuable.

* ci: Work around issues with dotnet-format not properly analyzing the source

* fix: Fix the logic of AsyncCoordinator and AsyncBarrier

* Prevent individual wait cancellations from canceling the entire barrier
* Propagate information about whether the wait was completed or cancelled, and whether any waiters were present when released

* fix: Remove superfluous acces to .Keys in InProcStepTracer

* refactor: Clean up AsyncCoordinator's use of AsyncBarrier
