hvm_funcs.hap_supported with the new function, to avoid accessing an

Turn them into static inline functions which evaluate to false when
CONFIG_HVM is not set. ARM won't be broken because ARM guests are set
to PV type in the hypervisor.
But ARM has plan to switch to HVM guest type inside the hypervisor, so
preemptively introduce CONFIG_HVM for ARM here.

Make sure hvm_enabled evaluate to false then provide necessary stubs,

The is_viridian_domain macro can't be turned into an inline function
easily, so instead its caller is modified to avoid unused variable
