Checked in part of MDE library instances following PI and UEFI. It includes:

1) UefiLib adds features of RFC 3066/Iso639 language string and driver model protocols installation.

2) PeiCoreEntryPoint following PI.

3) UefiDriverEntryPoint following UEFI/EFI.

4) PeiServicesTablePointerLib following PI for IPF and x86.

5) Remove many CommonHeader.h. If there is only one C file in module, we should add the common headers in C file instead of creating a new CommonHeader.h.
