MdeModulePkg/PartitionDxe: Add partition type guid to installed handle

Add the partition type GUID for every partition to the installed handle,
this is required per the UEFI specification.

"The firmware must add the PartitionTypeGuid to the handle of every
active GPT partition using EFI_BOOT_SERVICES.InstallProtocolInterface()."
