Trigger a window resize event when toggling sidebar state 

Other page elements outside of Vector should be notified that the
content area is changing size, in case they need to adjust the size of
fixed elements. Triggering window.resize should allow them to adapt
without needing to write Vector-specific code.

A specific case of this: the floating edit toolbar when VisualEditor is
open would be incorrectly sized / aligned if you toggled the sidebar in
edit mode.
