Add support for to display and edit N elements under a pointer

[davidanderle]

The IAR watch window has this nice feature to display N elements pointed to by a pointer, like myPtr;3
will show myPtr, myPtr+1, and myPtr+2. Additionally myArray;5,10 would display 5 elements, starting from the 10th element myPtr+10, myPtr+11, myPtr+12, myPtr+13, and myPtr+14.

Is this something that could be added to VSCode's watch window interpreter?

We plan on experimenting with bringing more debugger windows from Embedded Workbench into VS Code, starting with the live watch window requested in #3.

We could then also add the regular watch window from Embedded Workbench to VS Code, with all the same features such as this one.
