New API is disabled by default, to enable set CVAR Editor.EnableITFCursorOverrideSupport > 1

- as both legacy and new gizmos tick before the mode, they use an obsolete coordinate system when redering. As the Control Rig Mode caches the pivots on tick, we have to make sure we get up-to-date transforms.

- when created, the gizmo asks the mode manager to create a state target by calling FEditorModeTools::GetGizmoStateTarget(), which will create one if needed
- UEditorGizmoStateTarget::BeginUpdate() creates a new transaction + calls FEditorModeTools::BeginTransform() which will iterate thru the modes and ask them if they have anything to handle
- if they don't, the focused VPC still has the option of doing something (it doesn't by default, but some, like the level VPC, handle what they need to)

The new TRS gizmo system uses FEditorModeTools::GetShowWidget() to update the visible state of the gizmo.
However, for asset editors that don't override their default mode (as is the case with BP), the result is obtained from the FLevelEditorSelectModeWidgetHelper::ShouldDrawWidget function, which gets its data from the GCurrentLevelEditingViewportClient...
The FWidget rendering works mainly because it bypasses the result of FEditorModeTools::GetShowWidget() and relies on the value of FEditorViewportClient::GetWidgetMode() instead. VPCs like FSCSEditorViewportClient, for example, will change the widget mode dynamically according to the selection.
To change this behavior for new TRS gizmo without changing the current behavior, we swap the default mode with AssetEdModes::EM_AssetDefault if (and only if) FBuiltinEditorModes::EM_Default is one of the default modes and we're not dealing with the level editor's mode manager.
+ remove the direct uses of "Gizmos.UseLegacyWidget" in several places to ease the migration to user settings

two rotation modes available via Gizmos.RotateMode:
- 0: Pull, to rotate the object by pulling along the tangent to the circle (default)
- 1: Arc, to rotate the object by rotating around the gizmo center (like the screen space rotation does)

- the "pull" direction is now based on the closest projection to the rotation circle
- normal to that pull direction is removed to avoid poor drag behavior
- added a few temp cvars to experiment and fine tune the behavior
- Gizmos.DotThreshold 0.2: Dot threshold for determining whether the rotation plane is perpendicular to the camera view [0.2, 1.0]
- Gizmos.DebugDraw false: Displays debugging information.
- Gizmos.ProjectIndirect true: Project to the nearest point of the curve when handling indirect rotation.

- use the ViewAlignAxialMaxCosAngleTol property instead of the default one to enable per-element customization
- reduced the max partial angle of rotation handles so that they don't depth fight with the arcball handle on edges

New TRS Gizmo: hide gizmo if FEditorViewportClient::bShowWidget is false

- added ECoordSystem::COORD_Parent
- the mode manager's GetCustomDrawingCoordinateSystem overrides calculates the parent space transformation if required.
For the moment, there's no need to add anything at the ITF level, as everything is redirected to the VPC/Mode Manager thru the UEditorTransformProxy.
If the UTransformGizmo were to manage it locally, we'd probably have to add something similar to UCombinedTransformGizmo::bUseContextCoordinateSystem to make the TransformProxy responsible for managing the "local/parent" coordinate system.
