Handle early destruction of CanvasCaptureHandler

Fuzz testing showed that CanvasCaptureHandler can be destructed
earlier than CanvasCaptureHandler::VideoCapturerSource. Both instances
are owned by Blink side objects, and destruction sequence might be
different(oilpan).

CanvasCaptureHandler invalidates weakptrs in dtor() on main_render_thread.
We can check if weakptr is valid in StopCapture() that also runs
on main_render_thread.

BUG= 597077 
TEST=Added unittest "DestructHandler" to reproduce the fuzz case.
