IntelFrameworkModulePkg: DebugAssert enhancement

If the assert happens in a library, then it's hard to determine which module
using that library is generating that assert. Use gEfiCallerBaseName in
DebugAssert to display the module name.

In V2: Updated patch to use CopyMem instead of AsciiSPrint.
