Subject: [PATCH] fix: Add `Element::kind` method to `CosmicElement`

The default implementation always returned `Kind::Unspecified`. Instead,
we should pass this method through to the wrapped element.

This fixes the use of cursor planes. Now trace logs show Smithay
assigning an element to the cursor plane, and tools like `drm_info` show
the cursor plane with an `FB_ID` attached.
