[unity] Added support for Tint Black at all Spine URP shaders (2D and 3D) and at `Spine/Sprite` shaders. Closes #1705.

   * Added previously missing unlit URP 2D shader variant, available under `Universal Render Pipeline/2D/Spine/Skeleton`.
   * Added support for light cookies at `Universal Render Pipeline/Spine/Sprite` shader.
   * Timeline extension package: An additional Spine preferences parameter `Timeline` - `Default Mix Duration` has been added, setting newly added `SpineAnimationStateClip` clips accordingly, defaults to false. This Spine preferences parameter can be enabled to default to the previous behaviour before this update.
+  * Tint Black: Added support for [Tint Black](http://en.esotericsoftware.com/spine-slots#Tint-black) functionality at all Spine URP shaders (2D and 3D shaders) and at all standard pipeline `Spine/Sprite` shaders. This feature can be enabled via the `Tint Black` material parameter in the Inspector. Note: The URP Sprite shaders provided in the Spine URP Shaders extension UPM package require the latest version of the spine-unity runtime (package version 4.1.12, 2023-05-31 or newer) to display the added material parameters in the Inspector GUI.
  
 * **Breaking changes**
   * Made `SkeletonGraphic.unscaledTime` parameter protected, use the new property `UnscaledTime` instead.

 * **Changes of default values**
 
 * **Deprecated**
+  * Shader macro `RETURN_UNLIT_IF_ADDITIVE_SLOT` in `spine-unity/Shaders/Sprite/CGIncludes/ShaderShared.cginc` has been deprecated and will be removed in spine-unity 4.2. Use RETURN_UNLIT_IF_ADDITIVE_SLOT_TINT instead.
 
 * **Restructuring (Non-Breaking)**
