Adding proguard flags to avoid a11y methods getting stripped out.
AccessibilityNodeInfoCompat#obtain and AccessibilityNodeInfoCompat() are
both being stripped out by Proguard since DocsUI is not using these
methods. We are using these methods in tests to test a11y behaviors.
Test: Fixed AccessibilityTests.
