Subject: [PATCH] input: add cursor:warp_on_changeworkspace (#6480)

* input: add cursor:warp_on_changeworkspace

If enabled, warp the cursor to the last focused window on the workspace in the `changeworkspace' dispatcher, except if the cursor is currently on the WLR top layer.

Respect persistent warps.

* warp_on_change_workspace: check if focused layer is a window.
