Run by line partial implementation (microsoft#11608)
* Preliminary getting variables from the debugger * Implement updating as stepping * Get debugger and regular kernel to use same scripts * Put back old code and create experiment to enable/disable this * Implement experiment and begin on test for debugger * Finish fixing tests * Add news entry * Create multiplexer * Basic idea of glyph updating and control * Forget the svgs * Rework to go through interactive path * Highlight line kinda showing up * Fix variables to come out. * Fix ip line sticking around too long * Colors and icon working for ip * Implement F10 and F5 * Hover and step into icons * Remove unnecessary variables and support step into * Update frame id for variable * Fixup after merge * Exclude everything glob for just my code * Try fixing order for messages to debugger Remove exclusions as they mess up subsequent runs * Fix request problem and dark theme * Add news entry * Some extra comments and fix sonar problems * Add loc strings and make constants for code icons * Sonar problems and removing unused code * Change name to debugInfo * Try again to exclude the codicon files * Wrong base directory * Fixes from code review and run by line new icon * Fix functional test failures * Fix unit test failure (yay, caught a bug) * Fix stupid sonar warnings * Fix some more failing tests
