Reuse TouchableHighlight accessibility state without ARIA overrides (#59807)

Summary:

Use the supplied `accessibilityState` as the default and only build a new state object when an ARIA state prop overrides it. This avoids reconstructing a sparse state object with extra undefined fields when no ARIA override is supplied. ARIA precedence and the explicit `disabled` override are unchanged.

Refresh the affected snapshots and assert that the button keeps its empty accessibility state.
