Debugger: Finish handling of missing debug information.

Add a listener interface for LoadImageDebugInfoJob that allows it to request
user assistance based on its current state. Adjust callers to pass in said
listener accordingly.

Implement the aforementioned listener interface in TeamDebugger, and use the
loading state handler roster to find the appropriate handler / handle the request.

This implements most of what's needed for #10138, the main piece still missing
is for the dwarf handler to detect whether the image in question comes from a package,
and if so, to offer to install the corresponding debug information package rather than
locating the file manually, assuming such a package exists.
