Codechange: Remove initial colour from layouter cache. (#12728)

Browse Source 
Initial colour is now always TC_INVALID, which is substituted with the desired colour when drawing the layout line.

This allows strings which differ only by initial colour to use the same layout cache entry, increasing the efficacy of the cache.
