Fix inconsistencies in dispense events regarding stack size (#8653)

* Fix inconsistencies in dispense events regarding stack size

The javadocs for BlockDispenseEvent suggest the ItemStack is a single
item which is being dispensed. Before this fix, sometimes it was the whole
stack before a single item had been taken. This fixes that so the stack size
is always 1.

* Ensure stack size is correct in minecart and armor dispense behaviors
