When the level is locked, CanSelectElement evaluates to true, causing Unreal Engine to crash in the following two scenarios:
1. After locking the level, the user clicks on an ISM
2. After locking the level, the user drags the remaining gizmo on an ISM
The cause:
1. FSMInstanceElementLevelEditorSelectionCustomization::CanSelectElement evaluates to true because GEdSelectionLock seems always be false
2. DeselectAllActors in SetLocked does not recursively deselect the ISM components
The fix:
1. Determine whether the owner level is lockedin FSMInstanceElementLevelEditorSelectionCustomization::CanSelectElement
2. Use the typed element selection APIs to clear the current level's selection

* The same functionality is provided by the GizmoManipulationStarted and GizmoManipulationStopped.
* This simplifies the interface and removes the bespoke parameter added to branch between when manipulation starts and when it is ongoing to avoid expensive rendering invalidations
* There are some clients of TypedElementViewportInteractionGizmoManipulation::ApplyDeltaToActor, this CL does not address usage of this function. Doing so will require further adoption of TypedElements among those systems
