Introduce ObjectLoader and RSExecutable.
ObjectLoader loads an object file into memory.
ObjectLoaderImpl defines a set of format-independent interfaces
that a object file format loader has to provide.
ELFObjectLoaderImpl is a subclass of ObjectLoaderImpl and can be used
to load an ELF relocatable object built based on librsloader. It
directly uses the C++ APIs provided by librsloader instead of using
wrapped C APIs defined in librsloader.h
RSExecutable holds the build results of a RSScript.
