Add CTRL +/-/scroll shortcuts to adjust editor console font size

Add CTRL +/- and CTRL scroll shortcuts to increase/decrease editor console output text size. This font size is shared with the editor and serial/network monitor. Adjusting the font size on any of these will update them all.
Partially fixes #8615.
