Migrate shared-allocations made resident with makeMemoryResident

Browse Source 
Shared-allocations are currently migrated to GPU by the page-fault
manager when calling executeCommandLists. Allocations to migrate are
taken from the lists container. However, if a shared-allocation
has been made resident with zeContextMakeMemoryResident(), it is not
added to the list container, and hence it is not migrated to device.

So, add a container of resident allocations to the driver and migrate
them along with the other allocations.
