Add some LdFrameOptions for standard phones.

It would be cool if we can allow to simply pass some standard devices i.e. current iPhones, iPads or Pixel devices as presets to the golden utils.

An option to landscape them would also be great.

Adding some overlays for notches would also be great to test that layouts respect the SafeArea correctly(lists on landscape iPhones being cut off by notches is a common error). this would require reading some viewPadding / viewInset values from a simulator.

Previously I was able to produce t standard AppStore previews using the following sizes:

height: 2796 / 3.5,
width: 1290 / 3.5,
devicePixelRatio: 3.5

Added some default devices in Resolved with v1.4.0, could be extended still.

  factory LdFrameOptions.iPhone16() {
    return LdFrameOptions(
      width: 2556,
      height: 1179,
      uiMode: GoldenUiMode.screenWithSystemUi,
    );
  }

  factory LdFrameOptions.iPadPro12() {
    return LdFrameOptions(
      width: 2048,
      height: 2732,
      uiMode: GoldenUiMode.screenWithSystemUi,
    );
  }

  factory LdFrameOptions.googlePixel8() {
    return LdFrameOptions(
      width: 2400,
      height: 1080,
      uiMode: GoldenUiMode.screenWithSystemUi,
    );
  }

Looking at these numbers, I believe a devicePixelRatio for those probably makes sense
