output: check buffer in wlr_output_test

Check that buffer can be scanned out in wlr_output_test instead of
wlr_output_attach_buffer. This allows the backend to have access to the
whole pending state when performing the check.

This brings the wlr_output API more in line with the KMS API.

This removes the need for wlr_output_attach_buffer to return a value,
and for wlr_output_impl.attach_buffer.
