Hao Wu 7e4632a38f MdeModulePkg UfsPassThruDxe: Raise to TPL_NOTIFY when dealing async task 
This commit will raise the Tpl to TPL_NOTIFY when adding non-blocking SCSI
I/O requests to the asynchronous task list.

This commit will also raise the Tpl of asynchronous task polling timer to
TPL_NOTIFY.

These changes are made to match the behavior in ScsiDiskDxe driver.

Hao Wu 0350b57cf7 MdeModulePkg UfsPassThruDxe: Add Non-blocking I/O Support 
Previously, UfsPassThruPassThru function does not handle the 'Event'
parameter and blocking read/write operations are always executed.

This commit enables non-blocking read/write feature for UFS devices.

Feng Tian 0591696eff 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.
