Cheng Chang 0a0151fb99 Remove memcpy from RandomAccessFileReader::Read in direct IO mode (#6455) 
Summary:
In direct IO mode, RandomAccessFileReader::Read allocates an internal aligned buffer, and then copies the result into the scratch buffer. If the result is only temporarily used inside a function, there is no need to do the memcpy and just let the result Slice refer to the internally allocated buffer.
