When the caret is within a variable name, be able to add to watch, without having to to create a text selection (select some characters within the variable name)

1. Create new C++ project
2. Debug..
3. Place left click on variable name to place caret on / in variable.
4. Right click
5. No option to watch variable.
6. Select some characters of the variable name (even just 1)
7. Right click
8. Option to watch variable.

This is the behaviour of visual studio

1. Create new C++ project
2. Debug..
3. Place left click on variable name to place caret on / in variable.
4. Right click
5. Option to watch variable

Maybe we can use this same code that we use for finding a hover expression

vscode/src/vs/workbench/contrib/debug/browser/debugHover.ts

Line 398 in 9fa8f02

if (this.languageFeaturesService.evaluatableExpressionProvider.has(model)) {

@roblourens I've submitted a PR for this.

(Since it's been a while and no PR was submitted I take it as there's no ongoing work on this. If I'm wrong please ignore my PR.)
