vmstate: Define VARRAY with VMS_ALLOC
This allows dynamic allocation for migrating arrays.
Already existing VMSTATE_VARRAY_UINT32 requires an array to be
pre-allocated, however there are cases when the size is not known in
advance and there is no real need to enforce it.
This defines another variant of VMSTATE_VARRAY_UINT32 with WMS_ALLOC
flag which tells the receiving side to allocate memory for the array
before receiving the data.
The first user of it is a dynamic DMA window which existence and size
are totally dynamic.
