refactor Colors to be immutable

ColorScheme is now Immutable, making individual color updates less efficient, but making more common usage of colors more efficient

The reasoning behind this change is that the majority of apps wouldn't have updating individual colors as a main use case.

This is still possible but it will recompose more than before, in turn we significantly decrease the amount of state subscriptions through all of material code and will impact initialization and runtime cost of more standard use cases.
