[lldb] Make LLDB resilient against failing dyld introspection SPIs

Make LLDB resilient against failing dyld introspection SPIs:

 - dyld_process_create_for_current_task
 - dyld_process_snapshot_create_for_process
 - dyld_process_snapshot_get_shared_cache

These can all fail and return a nullptr. Instead of having an assert,
which doesn't really make sense, as we have no control over whether
these calls succeed or not, bail out gracefully and use the fallback
logic.
