[2D URP] Global Light with shadow settings enabled break batching

Global Light 2D with "Shadow Intensity" and "Shadow Volume Intensity" enabled, causes layer batching to break

Repro steps:
1. Open Batch2DURP.zip project in Unity 2021.1.1f1 or above
2. Open SampleScene and select Global Light 2D, switch Inspector to Debug mode
3. Observe "Shadow Intensity Enabled" and "Shadow Volume Intensity Enabled" checked
4. Open Frame Debugger and enable it
5. Under Draw All Renderers > Draw Layer Batch > RenderLoop.Draw, observe 2 Draw Dynamic calls as the capsules in scene are drawn separately

Expected results: Only 1 Draw Dynamic call, capsules in scene are drawn together/batched
Actual results: 2 Draw Dynamic calls, capsules in scene are not drawn together/batched
