fix: refactor text layout and quad generation in debug scene

- remove unnecessary code related to `instancedquad` from `src/scene/quad.rs`
- correct the function call to `add_text_layout` in `gen_debug_scene.rs`
- fix the initialization of `rect` in `gen_debug_scene.rs`
- adjust the position calculation in `gen_debug_scene.rs` for the `add_quad` function
- correct the function call to `add_text_layout` in `gen_debug_scene.rs` for `mask_layer`
