vmstate: Introduce VMSTATE_VARRAY_INT32_ALLOC

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.
