    tools/xen-foreign: Update the size for vcpu_guest_{core_regs, context}
    
    Commit 918b8842a852 ("arm64: Change type of hsr, cpsr, spsr_el1 to
    uint64_t") updated the size of the structure vcpu_guest_core_regs and
    indirectly vcpu_guest_context.
    
    On Arm, the two structures are only accessible to the tools and the
    hypervisor (and therefore stable). However, they are still checked
    by the scripts in tools/include/xen-foreign are not able to understand
    that.
    
    Ideally we should rework the scripts so we don't have to update
    the size for non-stable structure. But I don't have limited time
    to spend on the issue. So chose the simple solution and update
    the size accordingly.
    
    Note that we need to keep vcpu_guest_core_regs around because
    the structure is used by vcpu_guest_context and therefore the
    scripts expects the generated header to contain it.
    
    Fixes: 918b8842a852 ("arm64: Change type of hsr, cpsr, spsr_el1 to 
uint64_t")
