vmm: Create MemoryManager from restore data

Extending the MemoryManager::new() function to be able to create a
MemoryManager from data that have been previously stored instead of
always creating everything from scratch.

This change brings real added value as it allows a VM to be restored
respecting the proper memory layout instead of hoping the regions will
be created the way they were before.
