chore: improved formatting for C#

[slowikowskiarkadiusz]

Description
In this PR I resolve most issues with formatting of the generated C# code, accordingly to conventions I've observed as a C# programmer. The changes include:

• Opening bracket at classes/enums definition were at the same line as the class name. Now it's going to be generated in a line below
• A newline between dependencies (usings) and class definition
• Provided indentation in appropriate places (i.e. class members were being generated with the same indent as the class declaration)
• Each member of an enum is now in a separate line (this might seem a bit controversial, since basically neither of C# formatters is going to try to fix enum members that are all in a single line)
• Inserted/Removed newlines between particular parts of code (members of classes, enums definitions etc)

There might be also other issues than those that remain unresolved, but I think the generated code is going to look much more up to the standard.

No docs changes are required IMO.

Just a chore, I don't think it's worth making an issue

Gonna use fix: instead as we are changing the formatting that is rendered, and it need a new release 🙂
