1. Rename following library instances according to MDE Library Spec:
1) SerialPortLibNull => BaseSerialPortLibNull
2) DxeMemoryLib => UefiMemoryLib
3) DxeMemoryAllocationLib => UefiMemoryAllocationLib
4) CpuLib => BaseCpuLib
5) HiiLib => UefiHiiLib
6) IfrSupportLib => UefiIfrSupportLib
7) PeiPalCallLib => PeiPalLib
2. Add library instances to MDE package
