This PR does three things

- Right clicking within the gutter outside of the gutter fold area
bounds opens a breakpoint context menu
- Disabled breakpoints are now outline with the debugger accent color
instead of being fully colored at half opacity
- Clicking a breakpoint acts differently now
- Clicking a breakpoint while holding the platform modifier key will
disable/enable it
- Clicking a breakpoint hint while holding the platform modifier key
will set a disabled breakpoint
- Clicking a disabled breakpoint will enable it instead of deleting it

Release Notes:

- N/A
