Ard Biesheuvel 12a37b2ae1 MdePkg/BaseMemoryLib*: check for zero length in ZeroMem ()
Unlike other string functions in this library, ZeroMem () does not
return early when the length of the input buffer is 0. So add the
same to ZeroMem () as well, for all implementations of BaseMemoryLib
living under MdePkg/

This fixes an issue with the ARM implementation of BaseMemoryLibOPtDxe,
whose InternalMemZeroMem code does not expect a length of 0, and always
writes at least a single byte.
