Added ToShortNames and DisplayShortNames dictionary

[licon4812]

This pull request introduces support for handling "short names" for enum values in the Supernova.Enum.Generators project. The changes include updates to the source generator to process a new ShortName attribute, generate corresponding extension methods and dictionaries, and add comprehensive tests to validate the functionality.

resolves #138

Enhancements to Enum Source Generator:

• Added a new dictionary enumShortNames to store short names for enum members and updated the source generator to populate it when the ShortName attribute is provided. (Supernova.Enum.Generators/EnumSourceGenerator.cs: [1] [2]
• Introduced the ToShortName method to generate extension methods for converting enum values to their short names. (Supernova.Enum.Generators/EnumSourceGenerator.cs: [1] [2]
• Added the DisplayShortNamesDictionary method to generate a dictionary mapping enum values to their short names. (Supernova.Enum.Generators/EnumSourceGenerator.cs: Supernova.Enum.Generators/EnumSourceGenerator.csR395-R419)

Updates to Source Generator Helper:

• Added constants for the new ToShortNameFast extension method and DisplayShortNamesDictionary property. (Supernova.Enum.Generators/SourceGeneratorHelper.cs: Supernova.Enum.Generators/SourceGeneratorHelper.csR11-R17)

Test Enhancements:

• Updated test enums (UserType, UserTypeTest, and InternalUserTypeTest) to include the ShortName attribute for enum members. (test/Console.Test.Benchmark/Program.cs: [1] test/UnitTests/EnumGeneratorTest.cs: [2] test/UnitTests/InternalEnumGeneratorTest.cs: [3]
• Added unit tests for ToShortNameFast extension method, including cases for undefined values and default values. (test/UnitTests/EnumGeneratorTest.cs: [1] [2]; test/UnitTests/InternalEnumGeneratorTest.cs: [3] [4]
• Introduced benchmarks for the ToShortNameFast and ToShortNameNative methods to measure performance. (test/Console.Test.Benchmark/Program.cs: [1] [2]

Pull Request Overview

This pull request adds support for handling "short names" for enum values through a new ShortName attribute in the Supernova.Enum.Generators project. The enhancement enables developers to define and access abbreviated representations of enum values alongside existing display names and descriptions.

Key changes include:

• Introduction of short name processing in the enum source generator with dictionary storage and extension methods
• Addition of ToShortNameFast extension method and DisplayShortNamesDictionary property generation
• Comprehensive test coverage for the new short name functionality including edge cases
