output: rename impl->rollback to rollback_render
The output backend API is now mostly state-less thanks to the atomic hooks (commit and test). There is one exception though: attach_render. This function makes the rendering context current. However sometimes the compositor might decide not to render after attach_render (e.g. when there's nothing new to render to the back buffer). Thus wlr_output_rollback has been introduced to revert the pending state. Because the output backend API is mostly state-less, the only thing wlr_output_impl.rollback needs to do is revert the current rendering context. Rename the function to rollback_render to make this clear. Add a check in the common wlr_output code to only call rollback_render when attach_buffer has been previously called. On the long term, we'll be able to remove attach_render and rollback_render together.
