Port Color.compositeOver helper from compose.graphics

[okarmazin]

The existing Color.darkened arguably is the typical use case for compositing colors - designers sure do like their "5 % black over the background solid on hover". I think generalized Color.compositeOver is the next logical step.

Alternatively, Kobweb might benefit from porting the whole powerful Color system. If Kobweb already provides custom Color, it can as well have all the bells and whistles.

Thanks for the link to the Android color API!

I should definitely take a closer look at their code. I'll tag this with the 1.1 milestone because technically it isn't blocking anything and I haven't had any explicit requests for this or that color function, but that doesn't mean I wouldn't consider working on it or taking PRs for it before 1.0.
