If a modeset contains a render format change, use that instead of the current one stored in wlr_output.render_format. This fixes render_bit_depth configuration not being applied without a second modeset in Sway.
Now it takes a reference to a destination format
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.
