I'm not sure why? ClangdLSPServer knows about client capabilities so it made
sense to me to convert it there. Either way, it sounds like I should just
remove "HoverSupportsMarkdown" altogether if we're not going to use Markdown.

It looks odd. When I double them in the hover contents, the lines are displayed
as doubled and some extra backslashes are added on all non-empty lines except
the first line. Single new lines and correct backslashes are displayed
correctly when Markdown is used. We can just display multiline line macros as
one line until we want to handle Markdown (which is how exactly?).
