[DisplayList] Delete (publicly) unused DlColorColorSource (flutter/engine#56825)

Browse Source 
While recently updating the DlColorSource sources I noticed some questionably implementation choices in the Color variant of the color sources.

I then realized that there was no public use of these classes (other than mostly their own unit tests) and so they should be deleted to focus on implementing the variants that are actually used by Flutter.
