Fix trait codegen for List or Map traits with annotations or Javadocs

[joewyz]

Background

Trait codegen will generate duplicate @Deprecated annotation or Javadocs for the getValues() method if the trait is List or Map type.

For example, the following model:

/// This is my test list trait!!!
@trait
@deprecated(message: "Hey!", since: "Yesterday")
list MyListTrait {
    member: Integer
}

Trait codegen will produce the following code:

/**
 * This is my test list trait!!!
 *
 * @deprecated As of Yesterday. Hey!
 */
@Deprecated
@SmithyGenerated
public final class MyListTrait extends AbstractTrait implements ToSmithyBuilder<MyListTrait> {
    public static final ShapeId ID = ShapeId.from("example.traits#MyListTrait");

    private final List<Integer> values;

    private MyListTrait(Builder builder) {
        super(ID, builder.getSourceLocation());
        this.values = builder.values.copy();
    }

    //createNode()
    //fromNode()
    /**
     * This is my test list trait!!!
     *
     * @deprecated As of Yesterday. Hey!
     */
    @Deprecated
    public List<Integer> getValues() {
        return values;
    }
}

This PR fixed the above problem by add more checks in interceptors.
