Enhance memory copy logic for PEI core image read. The change uses CopyMem() library function for unshadowed version and uses inline implementation for a shadowed version. This reduces PE image reading time to 1/5 - 1/10 when code cache is disabled. The change also fixed a memory leak when allocating shadow space for image read function.
