  [LLDB] Add checks for ValueObjectSP in Cocoa summary providers

We saw a crash recently (rdar://problem/65276489) that looks related to an invalid ValueObjectSP in a summary providers in Cocoa.cpp e.g. NSBundleSummaryProvider(...).
This adds checks before we use them usually by calling NSStringSummaryProvider.
