[Feature]: Move to Non-Internal Work Item

[MrHinsh]

Currently there are still many moments when we use innerWorkItem and we need to move away to be able to remove the dependency on the ObjectModel.

Plan:

1. Remove innerWorkItem
2. Remove RefreshWorkItem, SaveToAzureDevOps, and ToWorkItem extension methods
3. All processing should happen on workItemData object...
