MdeModulePkg: Add UFS (Universal Flash Storage) Stack
It includes 4 drivers:
1. UfsPassThruDxe, which is a UEFI driver and consumes EFI_UFS_HOST_CONTROLLER_PROTOCOL and produces EFI_EXT_SCSI_PASS_THRU_PROTOCOL
2. UfsPciHcDxe, which is specific for pci-based UFS HC implementation and is a UEFI driver to produce EFI_UFS_HOST_CONTROLLER_PROTOCOL.
3. UfsBlockIoPei, which is a PEI driver and consumes EFI_UFS_HOST_CONTROLLER_PPI and produces EFI_PEI_VIRTUAL_BLOCK_IO_PPI.
4. UfsPciHcPei, which is specific for pci-based UFS HC implementation and is a PEI driver to produce EFI_UFS_HOST_CONTROLLER_PPI.
