MdeModulePkg/SdMmc: Add EDKII SD/MMC stack
This stack includes: 1. Dxe phase support by: 1) SdMmcPciHcDxe driver to consume PciIo and produce SdMmcPassThru. 2) SdDxe driver to consume SdMmcPassThru to produce BlkIo1/BlkIo2. 3) EmmcDxe driver to consume SdMmcPassThru to produce BlkIo1/BlkIo2/SSP. 2. Pei phase support 1) SdBlockIoPei driver to consume SdMmcHostController Ppi and produce VirutalBlkIo1&2. 2) EmmcBlockIoPei driver to consume SdMmcHostController Ppi and produce VirutalBlkIo1&2. 3) SdMmcPciHcPei driver to produce SdMmcHostController Ppi.
