Thomas Palmer c8b6f16d7d MdePkg: Create GetRandomNumber128 in RngLib
Declare GetRandomNumber128 in RngLib.h.
Create GetRandomNumber128 in BaseRngLib, which is simply calling
GetRandomNumber64 twice.

A GetRandomNumber128 function allows platforms with 128bit HWRNGs to
save on IO overhead that comes from having to prime the HWRNG device
before each read operation.
Using the HWRNG installed on the HP ProLiant m400 moonshot cartridge,
this will save about 50ms per RAW Entropy operation as compared with
calling GetRandomNumber64 twice.
