    xen/x86: move domctl.o out of PV_SHIM_EXCLUSIVE
    
    In order to fix CI error of a randconfig picking both PV_SHIM_EXCLUSIVE=y 
and
    HVM=y results in hvm.c being built, but domctl.c not being built, which 
leaves
    a few functions, like domctl_lock_acquire/release() undefined, causing 
linking
    to fail.
    To fix that, we intend to move domctl.o out of the PV_SHIM_EXCLUSIVE 
Makefile
    /hypercall-defs section, with this adjustment, we also need to remove
    redundant vnuma_destroy() stub definition to not break compilation.
    Above change will leave dead code in the shim binary temporarily and will be
    fixed with the introduction of CONFIG_DOMCTL.
    
    Fixes: 568f806cba4c ("xen/x86: remove "depends on !PV_SHIM_EXCLUSIVE"")
