perf: collect in apply_account_state is wasteful

[DaniPopes]

The following collect is wasteful, we should be able to reuse the map since all we're doing is retaining changed slots and shrinking the value type (EvmStorageSlot -> StorageSlot).

cc @rakita for ideas on how to do this.

Ideally fixing this wouldn't be too invasive.

	.storage

	.filter(|(_, slot)| slot.is_changed())
	.map(|(key, slot)| (key, slot.into()))
	.collect();
