Increasing amount of supported http methods

[Archivelit]

Motivation

The current version of LiteHttp supports only limited set of methods.
Adding more methods improves standards compliance and allows developers to handle more scenarios correctly, enhancing overall experience.

Notes

You can use MDN HTTP request methods documentation to add new ones.
You may refer to the existing examples.

Tasks

• Extend the RequestMethods class with method string constants.
• Add constants representation in RequestMethodsAsBytes class. The file with RequestMethodsAsBytes class location is src/Server/Core/Constants/src/LiteHttp/Constants/StringsAsByteArrays.cs.
• Extend IServer interface with new MapMethod methods and add documentation.
• Implement missing members in HttpServer and InternalServer.
• Write few tests for the new functionality (1-2 common cases are enough).
• Ensure your update does not contain breaking changes.
• Ensure code passes all tests.
