deps: Update vite to v8

[kakkokari-gtyih]

What

• できそうならしょぼめのrollup pluginとかはrolldownネイティブな書き方に置き換え終わってからマージしたい
  結局ほぼ全てのrollup/viteプラグインをアップデートした
• インライン化されたVue SFC出力に対してCSS Module定義削除が効いていなかったのを修正
• バックエンドのCSS参照が誤っており、初期ロードで読み込まれるmain以外のCSSが読み込まれなくなっていた問題を修正
• バックエンドのVite Manifestの保持をやめて、起動時に一度だけ必要なファイルの配列を計算してそれを保持するように

Vite v8 の簡単な測定結果は #17238 (comment)
