IntelSiliconPkg/VtdPmrPei: Add premem support.

Browse Source 
Remove memory discovered dependency to support both premem
VTD_INFO_PPI and postmem VTD_INFO_PPI.

If VTD_INFO_PPI is installed before memory is ready, this
driver protects all memory region.
If VTD_INFO_PPI is installed or reinstalled after memory
is ready, this driver allocates DMA buffer and protect rest.
