MemoryAllocationLib: For boundary case: “AllocationSize + OverAllocationSize >= 4G”

DxeMemoryAllocationLib: Change the behavior from returning NULL to ASSERT ()
PeiMemoryAllocationLib: Add ASSERT ()
I also add ASSERT () in Pei Service AllocatePool () to catch if allocation size > 64K
DebugLib:
Header file (DebugLib.h): Fix an issue in ASSERT_PROTOCOL_ALREADY_INSTALLED(Handle, Guid).  
In contrast with LocateProtocol (), the first & second parameter type of HandleProtocol () is EFI_HANDLE & EFI_GUID respectively.
UefiLib: 
For UnicodeStringDisplayLength (CONST CHAR8 *String), return 0 if String is NULL.
BasePrintLib: 
Add missing “EFIAPI” to UnicodeValueToString() and AsciiValueToString() and move their definitions from PrintLibInternal.c to PrintLib.c.
Fix the comments error(Maximum Length TIME”)
