std::stack is a wrapper that defaults to std::deque. As part of our
std::deque removal, an implementation of stack that uses base::circular_deque
is provided.

Rewrites trace_event_argument.cc usage of stack to use indices and a
circular_deque since it was relying on storage stability across updates.

Changes the PPAPI/V8 variable conversion code to avoid unstable usage
of a stack. Fixes a use-after-free in V8VarConverter::ToV8Value where
the reference to the top of the stack was dereferenced after popping it
off.
