Add context menu to live watch and contribute to text editor context menu for adding expressions to Live Watch window

[omarArm]

Fixes

• #519

Changes

• Added a context menu to the Live Watch window
• Added a copy expression command
• Added a "Add to Live Watch" command that adds to Live Watch window from source files, text editors, variables window, and watch window
• Showing data type of expression when hovering over it in Live Watch window
• Added a Show in Memory Inspector command in the context menu of Live Watch window

P.S. the user would have to right click on a window item in order to view the context menu. If he/she/they right click on the empty window in the background, it will not open up the context menu. However, that is consistent with other windows in VSCode (watch window, variables window, etc.)

P.S. I updated the command title in the different context menus to Add to Live Watch instead of Add To Live Watch without updating the screenshots
