output: introduce wlr_output_configure_primary_swapchain()
The goal is to simplify wlr_output by moving all of its rendering
API into separate helpers. Here is a first step to sunset
wlr_output_attach_render(). Instead, compositors call
wlr_output_configure_primary_swapchain(), wlr_swapchain_acquire(),
wlr_renderer_begin_with_buffer() and wlr_output_attach_buffer().
Note that compositors can supply a base struct wlr_output_state.
This is useful to allocate a buffer suitable for submission with
a modeset, for instance.
