Web Inspector: gradient editor should allow switching the units of the 'angle' parameter

[BJ Burg]

Supported units include degrees, grads, rads, and turn o_O

It looks like both the Gradient model object and the RegExp to match CSS gradient strings only support using "deg" as the units for angles.  Both will have to be updated.

Code changes look good (you did very neat things!) but needs a basic test as noted below.

> Source/WebInspectorUI/UserInterface/Models/Gradient.js:179
> +        if (components[0].length === 1) {

Since we are doing our own parsing in model code, I would expect that we have some basic test cases. Can you make a model test for Gradient that parses a few good and bad values for each angle unit of measure?

> Source/WebInspectorUI/UserInterface/Models/Gradient.js:259
> +        if (deg === 0)

I am surprised there are no tests for toString() either. Can you do something basic to test this?

> Source/WebInspectorUI/UserInterface/Views/GradientEditor.js:102
> +        this._angleUnitsConfiguration = new Map(angleUnitsData.map(({name, min, max, step}) => {

Wow! This took a bit of thinking, but I think i like it as a pattern for fixed configurations (as long as the pattern is consistently used). It's similar to the Java way of creating anonymous class instances for enums.

Nit: Please include the unknown value in the error message.
