Debug watch does not format list items using the format specifiers

[mika76]

Issue Description

As per #2713 you can use format specifiers (full list) on watch variables. But it does not work as expected on lists/arrays.

Steps to Reproduce

Watch a byte array in vscode c# omnisharp

Expected Behavior

The items should show as hex values

Actual Behavior

As you can see I added the ,h format specifier but only the main variable description changes, not the items.
