Summary:
D8842691 split AccessibilityTraits into multiple RN properties. However, the accessor code did not support REMOVING traits.
This results in buttons that were disabled (AccessibilityTraits & NotEnabled === true) never being enabled.
Fix the issue by making the split accessors properly mask in the bits, allowing you unset them without disturbing bits managed by the other accessor.
NOTE: setting AccessibilityTraits and AccessibilityRole or AccessibilityStates will still result in bugs.
