The hard-coded value, 10, is used for memory_listener_register().  Add symbolic
values for priority of struct MemoryLister.  Replace those hard-coded values
with symbols.

The background is KVM guest memory[1] or TDX support.  I'd like to add one more
memory listener whose priority is higher than the KVM memory listener.  And I
don't want to hard-code 10 + 1.

[1] KVM gmem patches

Isaku Yamahata (3):
  exec/memory: Add symbolic value for memory listener priority for accel
  exec/memory: Add symbol for memory listener priority for dev backend
  exec/memory: Add symbol for the min value of memory listener priority
