[v4,1/3] xen: kconfig: rename MEM_ACCESS -> VM_EVENT

Commit Message

Sergiy Kibrik March 14, 2025, 5:21 a.m. UTC 
Use more generic CONFIG_VM_EVENT name throughout Xen code instead of
CONFIG_MEM_ACCESS. This reflects the fact that vm_event is a higher level
feature, with mem_access & monitor depending on it.
