David Hildenbrand 5ead62185d memory: Make memory_region_is_mapped() succeed when mapped via an alias 
memory_region_is_mapped() currently does not return "true" when a memory
region is mapped via an alias.

Assuming we have:
    alias (A0) -> alias (A1) -> region (R0)
Mapping A0 would currently only make memory_region_is_mapped() succeed
on A0, but not on A1 and R0.

Let's fix that by adding a "mapped_via_alias" counter to memory regions and
updating it accordingly when an alias gets (un)mapped.

I am not aware of actual issues, this is rather a cleanup to make it
consistent.
