Vet every C++ lambda that captures only [this]

At least a few of them are definitely unsafe, in that they are deferred but don't guarantee the lifetime of `this`

I found these by grepping for (pretty much) every lambda usage in WebCore and then narrowing down to [this] captures:
grep -rn '\[.*\]\s*\((.*)\)\?\s*{\s*$' . | grep "\[this\]"
