[PATCH 09/15] x86/kconfig/64: Enable more virtualization guest options in the defconfig: enable Xen, Xen_PVH, Jailhouse, ACRN and Intel TDX

[Ingo Molnar]

Since the x86 defconfig aims to be a distro kernel work-alike with
fewer drivers and a shorter build time, refresh all the virtualization
guest Kconfig features, enabling paravirt spinlocks, and
enabling the guest support code for the following guests:

 - Xen
 - Xen_PVH
 - Jailhouse
 - ACRN
 - Intel TDX
