Already existing VMSTATE_VARRAY_INT32 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.
Introduce VMSTATE_VARRAY_INT32_ALLOC as we currently have for UINT32
and UINT16.
The first user of this variant will be the target/arm/machine.c cpreg
indexes/values arrays.
