output: always use hardware cursors if available
This changes the `wlr_output_impl.set_cursor` function to take a `wlr_texture` instead of a byte buffer. This simplifies the DRM and Wayland backends since they were creating textures from the byte buffer anyway. With this commit, performance should be improved when moving the cursor since outputs don't need to be re-rendered anymore.
