This pull request includes several changes to improve the handling of string capacities, normalize string values, and enhance test coverage. The most important changes include adding a new NormalizeString method, modifying the Capacity property, and updating the unit tests to use ITestOutputHelper.

String Handling Improvements:

• Added a NormalizeString method to ensure string values do not exceed the defined capacity in WebApiString and WebApiWString classes. [1] [2] [3] [4]

Capacity Property Updates:

• Introduced the Capacity property to OnlinerBase class to define the declared size of the string.
• Removed redundant Capacity property definitions from OnlinerString and OnlinerWString classes. [1] [2]

Unit Test Enhancements:

• Updated WebApiPrimitiveTests and its derived classes to use ITestOutputHelper for better test output logging. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16]

Dependency and Configuration Updates:
