Migrate materialColor* attributes into colors

The new color were already introduces in a previous CL ag/30322786

This CL is about replacing the attribute usage by the new color resources, which should work the same but cannot be overwritten, or styled, guaranteeing consistency across the OS.

The old attributes are also being removed here.
