Jiewen Yao f02c531967 IntelSiliconPkg/VTdInfoPpi: Let it follow DMAR table.
We notice that there is real usage in PEI to show
the graphic out. As such we need report RMRR table
in PEI to let VTdPmrPei driver skip the IGD UMA region.

Now the VTD_INFO PPI uses the same DMAR data structure.

Jiewen Yao 77562d13ac IntelSiliconPkg/include: Add VTD_INFO PPI.
This VTD_INFO_PPI is to provide VTD information in PEI.
As such, we can have a generic VTd driver.

It is a lightweight version DMAR table, but it does
not contain PCI device information.
