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.
