JDK-6793818 - JpegImageReader is too greedy creating color profiles
Description
The implementation of ICC_Profile tries to defer loading the data of the color profile, and it uses some predefined values for some profile properties for the standard profiles like sRGB, etc. If the application requests profile data then the ICC_Profile  class activates the profile and uses properties from that data.

Deferring mechanism for all profiles was added in JDK-6793818, but unfortunately, the color profile class was hardcoded incorrectly "CLASS_DISPLAY" for all profiles. However, the "CIEXYZ.pf" and "PYCC.pf" profiles should use "CLASS_COLORSPACECONVERSION".

Later the color "profiles/xxx.pf" were replaced in the JDK, and the actual type of the "CIEXYZ.pf" was changed to the "CLASS_ABSTRACT", but the deferring mechanism still uses "CLASS_DISPLAY".

As a result of this bug, the color profile reports different values before/after activations.
Comments
Fix request (11u) This change is one of the steps to update the CMM deferral machinery, The final goal will be backport this fix:https://bugs.openjdk.java.net/browse/JDK-6986863 The added test is red before the fix and green after. The jdk_desktop tests are green. The patch is not clean due to context conflict only, the code change is the same. PR: https://github.com/openjdk/jdk11u-dev/pull/793
