Routine Description:
Support routine for the PE/COFF Loader that reads a buffer from a PE/COFF file
Arguments:
FileHandle - The handle to the PE/COFF file
FileOffset - The offset, in bytes, into the file to read
ReadSize - The number of bytes to read from the file starting at FileOffset
Buffer - A pointer to the buffer to read the data into.
Returns:
EFI_SUCCESS - ReadSize bytes of data were read into Buffer from the PE/COFF file starting at FileOffset
