Improved debug inline values

[dimateos]

In C++ (dont know about other languages), the debug inline values are solved for the local scope, but it ignores local instance variables. Is quite common that a class access lots of its attributes rather than locally declared ones, so the feature seems lacking.

Prepending by "this->" does not help, in fact it shows the value of the whole instance. I can confirm this just happens with all variables idependently of the scope... this could be resolved to avoid clutter and only show the accessed value.

On top of that I would love options to modify which values are displayed. I can think of:

• Only last variable access (the clutter is a bit underwhelming, I decreased the default opacity)
• Only declaration (+ combine with the previous)
• Solve or not the local instance scope (I think it should be solved by default)
• Show adresses / values of referenced data
• Some padding to separate from the code
• Align all values at some column distabce (if the line is larger, just keep the previous behavior)
• There could be a separate color syle for nested variables (includes instance scope) to let the user change the shading.

The extension is able to tell vscode what the variables are, so you can file this on the cpp extension repo, thanks
