Add CFcommon.arch for the various arch's need for rcutorture.
    
In accordance with [1], [2] and [3], move x86 specific kernel option
CONFIG_HYPERVISOR_GUEST to CFcommon.arch, also move kernel option
CONFIG_KVM_GUEST which only exists on x86 & PowerPC to CFcommon.arch.

Thank you!  I have reverted the earlier version to queue this one.
Please check below to make sure that my usual wordsmithing did not mess
things up.

Mark, any suggestions for any needed ARM CFcommon.arch files?  Or does
moving out the x86/PowerPC-specific Kconfig options take care of things
for you guys?  (Hey, I can dream, can't I?)

							Thanx, Paul

commit 9d6767c47ce4de2ef817e47a5882748d8008ebe9
Author: Zhouyi Zhou <zhouzhouyi@gmail.com>
Date:   Wed Jun 19 23:06:58 2024 +0000

    rcutorture: Add CFcommon.arch for arch-specific Kconfig options
    
    Add CFcommon.arch for arch-specific Kconfig options.
    
    In accordance with [1], [2] and [3], move the x86-specific kernel option
    CONFIG_HYPERVISOR_GUEST to CFcommon.i686 and CFcommon.x86_64, and also
    move the x86/PowerPC CONFIG_KVM_GUEST Kconfig option to CFcommon.i686,
    CFcommon.x86_64, and CFcommon.ppc64le.
    
    The "arch" in CFcommon.arch is taken from the "uname -m" command.

I have studied the edition thoroughly, it is wonderful, and I learn a
lot through this
process!

I'm not aware of anything that we specifically need enabled, so pulling
out those bits should be everything -- I've given my Ack below.
