perf annotate: Add --code-with-type support for TUI

Until now, the --code-with-type option is available only on stdio.
But it was an artifical limitation because of an implemention issue.

Implement the same logic in annotation_line__write() for stdio2/TUI
and remove the limitation and update the man page.
