Kevin Tian 8eb9a48ac1 x86/fpu: Provide fpu_update_guest_xfd() for IA32_XFD emulation

Guest XFD can be updated either in the emulation path or in the
restore path.

Provide a wrapper to update guest_fpu::fpstate::xfd. If the guest
fpstate is currently in-use, also update the per-cpu xfd cache and
the actual MSR.
