Andrew Hutchings 468b2d473b MCOL-1016 Fix I_S calculations ...

* COLUMNSTORE_EXTENTS data_size now shows the total size on the highest
segment of an extent file. It also shows 0 bytes if HWM is zero so that
if there is more than one segment it doesn't show 8192 bytes for the
lower segments.
* COMPRESSION_RATIO was missing some data and using compressed data size
instead of file size (which is probably more realistic).
