nvmm-x86-vmx: improve the handling of CR4
 - Filter out certain features we don't want the guest to enable. This is
   for general correctness, and future-proofness.
 - Flush the guest TLB when certain flags change.

nvmm-x86: improve the handling of RFLAGS.RF
 - When injecting certain exceptions, set RF. For us to have an up-to-date
   view of RFLAGS, we commit the state before the event.
 - When advancing RIP, clear RF.
