[HAL] fix IREE_HAL_MAX_QUEUES to be number of bits in queue affinity type (#22702)

The computation of the number of bits in the queue affinity type
iree_hal_queue_affinity_t needs to use a multiplication by 8 to get from
the number of bytes to the number of bits. Before, it incorrectly used a
divison by 8. This resulted in IREE_HAL_MAX_QUEUES having an incorrect
value of 1 instead of 64.
