    Add missing debug logger entries for VIM

    The debug loggers are pre-created during process startup,
    and any that are missing can be created using lazy init.

    However the lazy init is not multi process safe and can
    lead to a subprocess deadlock during the import phase, which
    produces no logs or evidence that the thread is stalled.

    The workaround at the moment is to ensure that all the debug
    loggers defined at import time are configured to be setup when
    the process is created.

    There is still another cause of a stall. A separate commit
    will address it.
