Migrate lootdrop spawners to random spawners (#1543)

<!-- Вы можете прочитать Contributing.MD, если хотите узнать больше. -->

## Что этот PR делает
Рефакторит спавнеры лута под новый тип `/obj/effect/spawner/random` в
рамках избавления от легаси `/obj/effect/spawner/lootdrop`.
Фиксит лут у симпл воксов, который я случайно сломал во время мержа
апстрима.

## Почему это хорошо для игры
Баги плохо, новые технологии - хорошо.

## Тестирование
Поспавнил всякого, вроде спавнится, воксы дропают лут.

## Changelog

:cl: Maxiemar
tweak: Спавнеры лута мусора переведены на новую логику. Лут почти тот
же.
fix: Из симпл воксов снова корректно выпадает лут.
