[iOS] WKColorPicker's selection indicator doesn't always cover the selected swatch

[Aditya Keerthi]

On iPhone, the selection indicator should resize appropriately on rotation.

On iPad, the selection indicator should have rounded corners if it's at the corner of the color picker.

Nit - these two lines can just be `if ([_selectedColorButton superview] == matrixView)`

This looks like it'll get called many times, for every tick of the pan gesture recognizer. Is it possible to bail here if the selected color button hasn't actually changed, or do we always need to do this work?

We can bail early. Also makes sense to not redraw the selection if the same button is tapped twice.

Wait. I can't put it here because it will break the behavior from colorMatrixViewDidLayoutSubviews.

Nit - we generally prefer using std::abs here, instead of the CG equivalent.
