backends/native: Manage tablet cursors in backend

Instead of letting the wayland bits maintain an always-software
cursor renderer, let the cursor renderer be managed by the backend,
and only hook to it (as we do for pointer cursor) in the wayland
bits.

ATM, make the cursor renderer still always-software, although
ideally we should allow moving the HW cursor management between
renderers.
