HV: hypercall: revisit types in structure parameters

While fixing the MISRA C violations related to integral types, we have unified
the type of the following data:

    uint8_t:
        phys_pin, virt_pin, vpic_pin, ioapic_pin, vioapic_pin

    uint16_t:
        vm_id, pcpu_id, vcpu_id, vpid

    uint32_t:
        vector, irq

This patch revisits the types of the fields in vhm_request as well as the
structures used as parameters in the hypercalls, and make them aligned with the
types the hypervisor uses for such data. Reserved fields are added to keep the
size and layout of the structures. Implicit paddings are also made explicit as
reserved fields.
