There were too many patches to the Render system, it's really difficult to make further improvements. This PR clears the legacy problems and fix TODOs. 1. Rename `RenderContext.Type` to `RenderContext.MarkupType` to clarify its usage. 2. Use `ContentMode` to replace `meta["mode"]` and `IsWiki`, to clarify the rendering behaviors. 3. Use "wiki" mode instead of "mode=gfm + wiki=true" 4. Merge `renderByType` and `renderByFile` 5. Add more comments ---- The problem of "mode=document": in many cases it is not set, so many non-comment places use comment's hard line break incorrectly
