Don't recompile the entire rendergraph at swapchain recreation

[IAmNotHanni]

void VulkanRenderer::recreate_swapchain() {
    m_window->wait_for_focus();
    vkDeviceWaitIdle(m_device->device());

    // TODO(): This is quite naive, we don't need to recompile the whole frame graph on swapchain invalidation
    m_frame_graph.reset();
    m_swapchain->recreate(m_window->width(), m_window->height());
    m_frame_graph = std::make_unique<FrameGraph>(*m_device, m_command_pool->get(), *m_swapchain);
    setup_frame_graph();

I will close this issue because we will even compile the entire rendergraph on a per-frame basis, so not only during swapchain recreation. From what I understand this is state of the art, as it gives us more freedom over rendering in general.
