workqueue: fix enum type for gcc-13

In gcc-13, the WORK_STRUCT_WQ_DATA_MASK constant is a signed 64-bit
type on 32-bit architectures because the enum definition has both
negative numbers and numbers above LONG_MAX in it:

kernel/workqueue.c: In function 'get_work_pwq':
kernel/workqueue.c:709:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  709 |                 return (void *)(data & WORK_STRUCT_WQ_DATA_MASK);
      |                        ^
kernel/workqueue.c: In function 'get_work_pool':
kernel/workqueue.c:737:25: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  737 |                 return ((struct pool_workqueue *)
      |                         ^
kernel/workqueue.c: In function 'get_work_pool_id':
kernel/workqueue.c:759:25: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  759 |                 return ((struct pool_workqueue *)
      |                         ^

Change the enum definition to ensure all values can fit into
the range of 'unsigned long' on all architectures.
