Show loaded scripts in a custom explorer section #28521
Description
Today loaded scripts can be accessed via the "Open Loaded Script" action which uses a QuickPick UI.
With the new custom explorer support it is possible to show the loaded scripts in the VS Code explorer.
Challenge: since the QuickPick UI is modal it works well in face of concurrent debug sessions and does not need any events from the DAP.
Whereas a custom explorer is non modal and must be updated whenever scripts are loaded/unloaded and when switching between debug sessions.
