[jdk8u-dev] RFR: 8232225: Rework the fix for JDK-8071483

[Sergey Bylokhov]

This patch prevents possible name clashes for future backports. Right now the jdk8u-dev has the "Color" folder while the jdk11+ use the "color" folder. So depending on what file system backport is done the resulting folder could be different.

This is a proposal to backport the patch which had split the "Color" folder into "color" and "ColorClass". The patch is mostly clean except:
 - AlphaColorTest and XRenderTranslucentColorDrawTest are not present in JDK 8, both related fixes caused a couple of regressions, so no plans to backport it.
 - GetInstanceBrokenStream is added to the patch. In the upstream it was pushed after this fix, now we should place it in the correct folder "color" instead of "Color"

All tests green.
