XCUIElement provides method `coordinate(withNormalizedOffset:)` which returns XCUICoordinate objects with a position on the screen. The `screenPoint` is always computed correctly in any device orientation. But actions like tap or press interpret screen points as if the device was in portrait position.

element.coordinate(withNormalizedOffset: CGVector(dx: 0.5, dy: 0.5)).screenPoint

Above method will always return center position of the element on the screen on each orientation, but different elements will be tapped depending on the device orientation.
Problem probably exists because the `XCUIApplication` frame returns values as if the device was in the the portrait, but all its windows has correct frame. Output from the `debugDescription`:

Steps to Reproduce:
- Open Test application attached to this bug report with Xcode
- Run "TestUITests" test case
- In all tests, the same button is used to tap, but depending on the orientation different button was really tapped.

Expected Results:
In all orientations, the same button should be tapped.

Actual Results:
In portrait orientation Button A is tapped (correct)
In landscape left orientation Button C is tapped (incorrect)
In landscape right orientation Button B is tapped (incorrect)
In upside-down orientation Button D is tapped (incorrect)
