Use VK_KHR_dynamic_rendering

[doitsujin]

Keeping this as a draft for now since merging without support from stable drivers is not an option.

Tests pass on Nvidia, requires Vulkan beta driver 470.62.12 or later.

Needs more testing on RADV as its implementation of the extension comes along, and testing in actual games, although for that we'll need some sort of working Proton build with winevulkan support for this extension. I haven't checked if this is provided by proton-experimental bleeding edge yet.

LGTM. I think we can land this when we decide to.

Since branch update 8a7bfd6 all games just black-screen then crash.
Mesa-git on rx5700 amdgpu 5.16.9

Yes, this is a known issue with the current rebase since this breaks the pipeline feedback stuff that was added recently.

Found one bug for reference, caught by #1027:

    if (d3d12_command_list_has_depth_stencil_view(list))
    {
        /* Select new dsv_layout. Any new PSO write we didn't observe yet must be updated here. */
        dsv_plane_optimal_mask = list->dsv_plane_optimal_mask | list->state->graphics.dsv_plane_optimal_mask;
        dsv_layout = dsv_plane_optimal_mask_to_layout(list->dsv_plane_optimal_mask, // Should be dsv_plane_optimal_mask
                list->dsv.format->vk_aspect_mask);
    }
    else
    {
        dsv_plane_optimal_mask = 0;
        dsv_layout = VK_IMAGE_LAYOUT_UNDEFINED;
    }
