Data packs: a broken block and a sequence-less shear roll the world's loot tables

Game::block_loot_at rolled the game's own tables when the block's table has a
random_sequence, so a world data pack replacing blocks/stone was ignored.
Game::sequence_loot did the same for a table without a sequence (dispenser and
player shearing, brushing). Both now roll world_items!, as vanilla's
reloadableRegistries().getLootTable does.

Fixes #6777
