  Followup to 270854 at main: remove some hard-coded default colors in `WKExtendedTextInputTraits`

Reviewed by Richard Robinson.

The following three properties:

```
-insertionPointColor
-selectionBarColor
-selectionHighlightColor
```

...are actually nullable on `UIExtendedTextInputTraits`, and setting them to `nil` allows UIKit to
fall back to default colors. As such, we can avoid hard-coding default values here and just set
these properties to `nil`.

* Source/WebKit/UIProcess/ios/WKExtendedTextInputTraits.mm:
(-[WKExtendedTextInputTraits setSelectionColorsToMatchTintColor:]):
(WebKit::defaultInsertionPointColor): Deleted.
(WebKit::defaultSelectionGrabberColor): Deleted.
(WebKit::defaultSelectionHighlightColor): Deleted.
