Add bold highlights for section name comments `%%`

[wohenbushuang]

Is your feature request related to a problem? Please describe. if you comment with %% in the begining of lines, Matlab editor will recognize it as a section divider, and mark the comment line with bold font. But in vscode there is no visual difference, and thus I find it hard to quickly locate the beginnings of different sections.

Describe the solution you'd like As in Matlab editor does, make the comment line bold. Or highlight it with some bright colors, as other comment extensions of vscode does (Eg. better commments).
