Support wrapping comment lines

[make1980]

Support wrapping single line comment and multi-line comments based on line width. This commit fixes #1352

There are a whole lot of edge cases that need to get addressed. This changed too many files to easily review it via the web link. I added a few of them below. - https://github.com/belav/csharpier-repos/pull/114/files#diff-a6ea5fd61ca05285c0b3163f7a11ca3aadea54eb5a2f77ad10fc2a7f0cab86d1

The last one is concerning, if someone comments out a big block of code, it is reformatted with line breaks, and then the uncomment it, will it still be valid code? I believe that is true.

There are also failing tests to look at.

I didn't look too closely at the code, but did see a lot of explicit variable types. var needs to be used everywhere it is possible.

Documentation comments end up with a // instead of ///

        /// <param name="messageFormat">A composite format string explaining the reason for the exception.</param>

        /// <param name="messageFormat">A composite format string explaining the reason for the
        // exception.</param>

Should this be combining short comments into a single comment? Otherwise there is no way to avoid this.

                // Documentation does not state the behavior when the stream is closed. The NetworkStream
                // implementation suggests the contract should be to throw ObjectDisposedException when the stream is
                // closed.

                // Documentation does not state the behavior when the stream is closed. The NetworkStream
                // implementation suggests the contract should be to throw ObjectDisposedException when the stream
                // is
                // closed.

But if we do start combining lines, then this is going to get clobbered together. And also combining lines is going to really screw with commented out code.

This is one examble of what it does to commented out code

        //[Variation("ReadSubtree Test on Root", Pri = 0, Params = new object[]{"root", "", "ELEMENT", "", "", "NONE" })]
        //[Variation("ReadSubtree Test depth=1", Pri = 0, Params = new object[] { "elem1", "", "ELEMENT", "elem5", "", "ELEMENT" })]
        //[Variation("ReadSubtree Test depth=2", Pri = 0, Params = new object[] { "elem2", "", "ELEMENT", "elem1", "", "ENDELEMENT" })]
