feat: improve optional value

[wangl-cc]

• Rename OptionalInput to Optional;
• Rename deps to conditions in Optional;
• Rename input to value in Optional and can be any boxed MAAValue;
• Fix initialize order of values in an object: The current sort implementation is incorrect. The sort_by function is only suitable for sorting elements with a total order, whereas the dependencies exhibit a partial order. In the current implementation, we define a total order that combines dependencies and key names, which is not transitive, even in the absence of circular dependencies. For instance, if A depends on B, B depends on C, and C depends on D, then it should be A < B < C < D. However, C and A are both Optional and do not directly depend on each other. Consequently, they will be compared by their keys, and the order may be C > A, which contradicts the dependencies. We should not use keys to compare elements, but rather the dependencies. Although the dependencies are a partial order, we can sort them using a topological sort (depth-first search).
• Improve the macro object! that can be used to create optional.
