RFR: 8281419: The source data for the color conversion can be discarded

Tue Feb 8 05:54:36 UTC 2022

When we convert the image from one color profile to another one we copy data to the temp array, and after conversion, we commit both(src and dst). But the source array could be discarded since we do not(should not) change it. 

Tested on windows (fastest result after a few runs). ThreadsMAX is 32 threads. The test is just a "ColorConvertOp.filter()" for the opaque buffered image.
