OvmfPkg: Update PlatformPei to support Tdx guest
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
OvmfPkg/PlatformPei is updated to support Tdx guest. There are below
major changes.
- Set Tdx related PCDs
- Publish Tdx RamRegions
In this patch there is another new function BuildPlatformInfoHob ().
This function builds EFI_HOB_PLATFORM_INFO which contains the
HostBridgeDevId. The hob is built in both Td guest and Non-Td guest.
