tests/wl_surface: Test wl_buffer.release is called

When the buffer is removed from a surface or replaced.

I added to WssyBuffer which I assume was created for this purpose.

I also added create_buffer_with_data to wrap pool.send_constructor with a supplied ObjectData, I'm not completely happy with this design. An alternative would be returning a (WssyBuffer, WlBuffer) pair or directly calling send_constructor for tests where wl_buffer.release is relevant.

Clippy fails as shm_pool_create_buffer_with_data takes 1 too many argument, dimentions: (i32, i32) could fix this.

Currently both tests pass for anvil. Mir on the other hand doesn't wl_buffer.release in the buffer_release_on_detach_buffer case.
