Add debuginfod launch option to cppdbg debugger schema (#14471)

Add the `debuginfod` configuration option to both launch and attach
configurations for the cppdbg debugger type. This exposes the MIEngine
debuginfod settings (enabled/timeout) so users can control GDB's
debuginfod behavior and prevent hangs when debuginfod servers are
unreachable.
