Camera events on SRP

In the built-in renderpipeline we can add some functions related to rendering to a `Monobehaviour` that will be fired. Rider knows about these events.
However, when using URP, HDRP or any scriptable renderpipeline, these won't get called (https://forum.unity.com/threads/camera-onprecull-onprerender-not-working.755516/).
It would be nice if Rider could give us a warning (or error) if we try to use the `OnPreRender` function (for example) when we are using a scriptable render pipeline. In that case we're supposed to use the delegates that `RenderPipelineManager` has (https://docs.unity3d.com/ScriptReference/Rendering.RenderPipelineManager.html).

I'm pretty sure you can use `GraphicsSettings.renderPipelineAsset` (https://docs.unity3d.com/ScriptReference/Rendering.GraphicsSettings-renderPipelineAsset.html) to determine if a scriptable renderpipeline is used.

No file or test is named in the issue. Start by locating the Unity inspections for MonoBehaviour message methods, then compare the documented OnPreRender behavior with GraphicsSettings.renderPipelineAsset and RenderPipelineManager; done means the unsupported callback is diagnosed for scriptable render pipelines with guidance toward the relevant delegates.
