"Show in Memory Inspector" context menu entry for Watch window

[jreineckearm]

Description

Since version 1.103.x, VS Code supports context menu contributions to the Watch window.
We should add "Show in Memory Inspector" context menu functionality similar to what we have for the Variables window (see here).

Note that the command handler may need to be different from the Variable window's one to deal with expressions instead of variables on DAP level.

Thank you for your contribution, @xoriath ! I'll review and provide feedback early next week.

Unfortunately I cannot assign the issue to you as this is your first contribution to the project (there is a tiny chance I can once you commented on this issue). Assigning to myself for the time being to indicate it's in progress.
