output: always use hardware cursors if available

Browse source 
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.
