Loads a PE/COFF image into memory.
Retrieves and returns a pointer to the entry point to a PE/COFF image that has been loaded
into system memory with the PE/COFF Loader Library functions.

Retrieves the entry point to the PE/COFF image specified by Pe32Data and returns this entry
point in EntryPoint. If the entry point could not be retrieved from the PE/COFF image, then
return RETURN_INVALID_PARAMETER. Otherwise return RETURN_SUCCESS.
If Pe32Data is NULL, then ASSERT().
If EntryPoint is NULL, then ASSERT().
@retval EFI_SUCCESS if the EntryPoint was returned
