tools/workqueue: add CACHE_SHARD support to wq_dump.py

Browse Source 
The WQ_AFFN_CACHE_SHARD affinity scope was added to the kernel but
wq_dump.py was not updated to enumerate it. Add the missing constant
lookup and include it in the affinity scopes iteration so that drgn
output shows the CACHE_SHARD pod topology alongside the other scopes.
