Use material name for mesh entity's Name when available (#19287)
# Objective

Fixes #19286

## Solution

Use material name for mesh entity's Name when available

## Testing

Test code, modified from examples/load_gltf.rs
```rust
//! Loads and renders a glTF file as a scene.

use bevy::{gltf::GltfMaterialName, prelude::*, scene::SceneInstanceReady};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_systems(Startup, setup)
        .add_observer(on_scene_load)
        .run();
}

fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
    commands.spawn((
        Camera3d::default(),
        Transform::from_xyz(0.7, 0.7, 1.0).looking_at(Vec3::new(0.0, 0.3, 0.0), Vec3::Y),
    ));

    commands.spawn((DirectionalLight {
        shadows_enabled: true,
        ..default()
    },));

    commands.spawn(SceneRoot(asset_server.load(
        GltfAssetLabel::Scene(0).from_asset("models/FlightHelmet/FlightHelmet.gltf"),
    )));
}

fn on_scene_load(
    trigger: Trigger<SceneInstanceReady>,
    children: Query<&Children>,
    names: Query<&Name>,
    material_names: Query<&GltfMaterialName>,
) {
    let target = trigger.target();

    for child in children.iter_descendants(target) {
        let name = if let Ok(name) = names.get(child) {
            Some(name.to_string())
        } else {
            None
        };
        let material_name = if let Ok(name) = material_names.get(child) {
            Some(name.0.clone())
        } else {
            None
        };

        info!("Entity name:{:?} | material name:{:?}", name, material_name);
    }
}
```
