Part of the first step in redesigning the `ColorPicker` component on `native` to match the `ColorSelector` component on `web` introduced by @atul.
`ColorSelector` is a new component that will work with `ColorSelectorButton` to replace `ColorPicker` on `native`. This diff handles color layout, and adding `onPress` handling and active state functionality will be applied in later diffs.
