Object Mode: move to workspace struct

- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
  (context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
  this does work on a basic level though.
