feat(ScreenSpinner): add overlay mode

[BlackySoul]

• close [Feature][ScreenSpinner]: Поддержать overlay режим  #6952

---

• e2e-тесты
• Дизайн-ревью
• Документация фичи

Изменения

• добавлен проп mode, который отвечает за режим отображения
• исправлен токен для тени в режиме mode=shadow в соответствии с ДС
• иногда цвет спиннера должен переопределяться контекстом сверху, для этого завела проп noColor
• объединила скриншотные тесты

---

Пришлось немного перетрясти структуру - стайлгайдист не смог смапить название ScreenSpinner:

Поэтому все подкомпоненты вынесла в отдельные файлы
