[analysis_server] Update color handling for recent Flutter Color class changes In https://github.com/flutter/engine/pull/54714 the "int value" that was used for storing the color values for a Flutter color was removed and replaced with `double red, double green` etc. The color computer used the `value` field so this stopped it from computing any colors for previews in LSP clients. No tests broke because the tests here use a mock version of the Color class that still had `value`. This change updates the mock Color class to match the new Flutter implementation, and updates the computer to use the red/green/blue doubles instead of parsing from an int. It also adds support for the new `Color.from()` constructor that was also recently added.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
