<AWT Dev> RFR: 8260695: The java.awt.color.ICC_Profile#getData/getData(int) are not thread safe

[Sergey Bylokhov]

Both methods are implemented in a similar way.
 1. Requests the size of the profile/tag data
 2. Creates an array of the correct size
 3. Requests the data and copy it to the array

If the data will be changed concurrently between steps 2. and 3. then we will get a mismatch between the array and copied data. 

In the fix, all steps above are merged to just one step return the data when requested.
