Timothy Flynn 8ec7b4401a LibWeb: Add a helper class to work around empty execution context stack
We've peppered this workaround around the code base as needed in a few
different ways. This adds a helper class to perform this workaround in
order to simplify doing so, and ensure cleanup occurs in a RAII fashion.
This also makes it easier to grep for places where this workaround is
employed.
