Update to Chromium version 86.0.4240.198

If a WeakPtr references an already-destroyed object, operator-> and
operator* end up simply dereferencing nullptr. However, dereferencing
nullptr is undefined behavior and can be optimized in surprising ways
by compilers. To prevent this from happening, add a defence of last
resort and CHECK that the WeakPtr is still valid.
