[Feature Request]: ability to set watchpoint on variables (VSC-1583)

[bryghtlabs-richard]

Is your feature request related to a problem? Please describe.
I'd like to be able to set a watchpoint to break the program anytime a specific variable changes.

Describe the solution you'd like
I'd like to be able to right-click on a variable, either in a watch view or code, and choose to set a watchpoint(or data-breakpoint in Visual Studio lingo).

Alternatively, something similar to Visual Studio's Debug->New Breakpoint->Data Breakpoint->Type in the symbol would also work.

Describe alternatives you've considered
I don't think I have any good alternatives. We don't have enough pins to use an external debugger. It is possible to set watchpoints using plain GDB, but I like the ability to view source is VSCode. I've looked at the various breakpoint options but they all appear to be instruction-breakpoint related.
