KVM: VMX: Bury all of the VMX preemption timer code under CONFIG_X86_64=y

Double down on using the VMX preemption timer only for 64-bit kernels, and
bury the setup and runtime adjustment code, and all global variables, under
CONFIG_X86_64=y.  This will allow addressing a widespread Intel erratum
without running afoul of unused-but-set-variable and __udivdi3() errors on
32-bit kernels.

No functional change intended.
