Provide source level debug ability in *unix environment.
[Background]
The UnixPkg provide an simulator in *unix. To support source level debug, we need force all modules be built as ELF shard objects and dynamically load all of modules using dlopen(). For peicore, peim and dxecore, we provide a wrapper to provide PeCoffLoader interface
