workqueue: Update documentation as per system_percpu_wq naming

Browse Source 
Update documentation to use "per-CPU workqueue" instead of
"global workqueue" to match the system_wq to system_percpu_wq
rename. The workqueue behavior remains unchanged; this just
aligns terminology with the clearer naming.

Fixes: a2be943b46 ("workqueue: replace use of system_wq with system_percpu_wq")
