Fix: Correct Layout Behavior for Combined align-content and align-items (#47732)

Browse Source 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47732

This pull request addresses the issue where combining align-content and align-items properties resulted in incorrect layout behavior in Yoga version 3.1.0, as reported in [Issue https://github.com/facebook/yoga/issues/1739](https://github.com/facebook/yoga/issues/1739).

# Changes Made:

Alignment Logic Update: Modified the alignment calculations to ensure that the combination of align-content and align-items properties produces the expected layout, consistent with CSS Flexbox standards and previous Yoga versions.

Test Cases Added: Introduced new test cases to cover scenarios involving various combinations of align-content and align-items properties to prevent future regressions.

# Testing:

All existing tests pass successfully.

New test cases confirm that the layout behaves as expected when align-content and align-items are used together.

# Impact:

This fix ensures that layouts using both align-content and align-items properties render correctly, aligning with the behavior observed in Yoga version 1.19.0 and standard web browsers.
