  1. cpu: require PGE and NX support 

    All platforms capable of virtualization support PGE and NX, so there is
no reason to make these features optional in the SVSM code base.

  2. cpu/tlb: do not broadcast per-cpu TLB flushes 

    VM ranges that are specific to a single CPU do not require TLB
invalidations to be broadcast to multiple processors.  This is
especially important during the early boot phase when no other
processors are online and when the infrastructure required to broadcast
TLB invalidations may not yet be fully initialized.  The same is true
for temporary mappings established in a per-CPU address range.
