    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.
