OvmfPkg/ResetVector: wire up 5-level paging for TDX
BSP workflow is quite simliar to the non-coco case.
TDX_WORK_AREA_PGTBL_READY is used to record the paging mode:
1 == 4-level paging
2 == 5-level paging
APs will look at TDX_WORK_AREA_PGTBL_READY to figure whenever
they should enable 5-level paging or not.
