Add a new renderer API
Goals: - Extensibility: we need to be able to add new params to the calls to render a texture/rect. For instance we'll need to add fences to the render texture operation for explicit sync purposes. - No implicit state: no more bind_buffer, begin, end. - No matrices: these hurt Pixman and we don't need them. - Clip regions for optimized damage repainting. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3188
