Message:

[iOS] Make AccessibilityReduceMotion test case work on iOS
​https://bugs.webkit.org/show_bug.cgi?id=225244
<rdar://problem/77589455>

Reviewed by Per Arne Vollan.

New tests for Accessibility-related features were added in Bug 215664, but only for macOS.
We support these same features on iOS, and should have test coverage.
