debugger: Show language icons in debug scenario picker (#30662)

We attempt to resolve the language name in this order

1. Based on debug adapter if they're for a singular language e.g. Delve
2. File extension if it exists
3. If a language name exists within a debug scenario's label

In the future I want to use locators to also determine the language as
well and refresh scenario list when a new scenario has been saved

Release Notes:

- N/A
