scene: try to import buffers as textures before rendering
The wlroots APIs currently don't allow importing/uploading a buffer
during rendering operations. Scene-graph buffer nodes need to turn
their wlr_buffer into a wlr_texture at some point. It's not always
possible to do so at wlr_scene_buffer creation time because the
scene-graph may have zero outputs at this point, thus no way to
grab a wlr_renderer.
Instead, add scene-graph buffers to a pending list and try to import
them in wlr_scene_output_commit.
