Consolidate color conversion into color utils

[tobrun]

In multiple places in the code base we currently convert from an Android int color to rgba float[] or string equivalent. We have 2 implementations of these in our codebase ColorUtils and PropertyFactory. In #12377, we are also adding Android int color conversion to rgba variant that gl uses (values range from 0-1).

For 4.3.0, we should start deprecating the PropertyFactory variant.
Cleanup can happen as part of next major release.
