Remove third-party dependency on react-native-hsv-color-picker

[derekblank]

Is your feature request related to a problem? Please describe.
The react-native-hsv-color-picker library is an unmaintained forked third-party dependency that uses no native resources, and is only used in one Gutenberg file (the native color picker). The library is small enough that it could be implemented directly within our code as part of the native color picker (or as a native color picker utility).

Removing the third-party dependency would simplify future React Native upgrades.

Describe the solution you'd like

1. Take the source of react-native-hsv-color-picker and incorporate it as part of the native Gutenberg color picker files.
2. Convert the code from a class to a function component in the process, and modify any library code that would better suit the project.
3. Remove the third-party react-native-hsv-color-picker package dependency and delete the repo.

Describe alternatives you've considered
Continue to use the forked third-party library as-is, or use the original react-native-hsv-color-picker library as a non-forked dependency.

Thanks for opening the ticket @derekblank 🙇 ! I also considered this when reviewing the dependencies for the React Native upgrade. It shouldn't be too complex to implement a picker similar to what we have in https://github.com/lukewalczak/react-native-hsv-color-picker/blob/master/src/HsvColorPicker.js.

Just a heads up -- I've started working on this issue during downtime in between other tasks.

Resolved in WordPress/gutenberg#53329.

Now that we no longer use the forked repository https://github.com/wordpress-mobile/react-native-hsv-color-picker, I'm going to archive it.
