OvmfPkg/ResetVector: Clear SEV encryption bit for non-leaf PTEs
Future changes will make use of CpuPageTableLib to handle splitting
page table mappings during SEC phase. While it's not strictly required
by hardware, CpuPageTableLib relies on non-leaf PTEs never having the
encryption bit set, so go ahead change the page table setup code to
satisfy this expectation.
