debugger: Update the default layout (#31057)

- Remove the modules list and loaded sources list from the default
layout
- Move the console to the center pane so it's visible initially

Release Notes:

- Debugger Beta: changed the default layout of the debugger panel,
hiding the modules list and loaded sources list by default and making
the console more prominent.
