Relintai 58539a22b6 Backported from Godot4: Node3D gizmo improvements
* Clean-up of node_3d_editor_plugin.{h,cpp}: removed unused code, fixed some bugs.
* Moved node_3d_editor_gizmos.{h,cpp} to editor/plugins.
* Added support for multiple gizmos per node. This means custom gizmos will no longer override the built-in ones and that multiple gizmos can be used in more complex nodes.
* Added support for handle IDs. When adding handles to a gizmo, an ID can be specified for each one, making it easier to work with gizmos that have a variable number of handles.
* Added support for subgizmos, selectable elements that can be transformed without needing a node of their own. By overriding _subgizmo_intersect_frustum() and/or _subgizmo_intersect_ray() gizmos can define which subgizmos should be selected on a region or click selection. Subgizmo transformations are applied using get/set/commit virtual methods, similar to how handles work.

- Note: MeshDataResourceEditor is now kind of painful to use, it will be fixed a bit later.

<brief_description>
Used by the editor to define Spatial gizmo types.
</brief_description>
<description>
[EditorSpatialGizmoPlugin] allows you to define a new type of Gizmo. There are two main ways to do so: extending [EditorSpatialGizmoPlugin] for the simpler gizmos, or creating a new [EditorSpatialGizmo] type. See the tutorial in the documentation for more info.
To use [EditorSpatialGizmoPlugin], register it using the [method EditorPlugin.add_spatial_gizmo_plugin] method first.

<method name="add_material">
<return type="void" />
<argument index="0" name="name" type="String" />
<argument index="1" name="material" type="SpatialMaterial" />
<description>
Adds a new material to the internal material list for the plugin. It can then be accessed with [method get_material]. Should not be overridden.
</description>
</method>
<method name="can_be_hidden" qualifiers="virtual">
<return type="bool" />
<description>
Override this method to define whether the gizmos handled by this plugin can be hidden or not. Returns [code]true[/code] if not overridden.

<method name="commit_handle" qualifiers="virtual">
<return type="void" />
<argument index="0" name="gizmo" type="EditorSpatialGizmo" />

<argument index="3" name="cancel" type="bool" default="false" />
<description>
Override this method to commit a handle being edited (handles must have been previously added by [method EditorSpatialGizmo.add_handles] during [method _redraw]). This usually means creating an [UndoRedo] action for the change, using the current handle value as "do" and the [code]restore[/code] argument as "undo".
If the [code]cancel[/code] argument is [code]true[/code], the [code]restore[/code] value should be directly set, without any [UndoRedo] action. Called for this plugin's active gizmos.

<description>
Override this method to commit a group of subgizmos being edited (see [method _subgizmos_intersect_ray] and [method _subgizmos_intersect_frustum]). This usually means creating an [UndoRedo] action for the change, using the current transforms as "do" and the [code]restore[/code] transforms as "undo".
If the [code]cancel[/code] argument is [code]true[/code], the [code]restore[/code] transforms should be directly set, without any [UndoRedo] action. Called for this plugin's active gizmos.

<description>
Override this method to set the gizmo's priority. Gizmos with higher priority will have precedence when processing inputs like handles or subgizmos selection.
All built-in editor gizmos return a priority of [code]-1[/code]. If not overridden, this method will return [code]0[/code], which means custom gizmos will automatically get higher priority than built-in gizmos.

<return type="void" />
<argument index="0" name="gizmo" type="EditorSpatialGizmo" />

<description>
Override this method to allow selecting subgizmos using mouse drag box selection. Given a [code]camera[/code] and a [code]frustum[/code], this method should return which subgizmos are contained within the frustum. The [code]frustum[/code] argument consists of an [code]Array[/code] with all the [code]Plane[/code]s that make up the selection frustum. The returned value should contain a list of unique subgizmo identifiers, these identifiers can have any non-negative value and will be used in other virtual methods like [method _get_subgizmo_transform] or [method _commit_subgizmos].
